Aita for backing my sil up and kicking my wife’s friend out of house for touching my niece

In a home meant to be a sanctuary of love and support, tension has quietly taken root. The narrator’s small family, intertwined with the lives of his wife and sister-in-law, struggles under the weight of an unwelcome presence—a friend whose reckless disregard for boundaries threatens the peace they cherish.

The breaking point came when carelessness crossed a sacred line: a drunken visitor, ignoring simple hygiene, reached out to a fragile infant. In that charged moment, the family’s patience shattered, revealing the raw, protective instinct that binds them together against the intrusion of chaos.

Aita for backing my sil up and kicking my wife's friend out of house for touching my niece

My wife and I have been married for 3 years and my wife and I and my SIL (wife’s sister) we all live together. She has 2 kids, a 2-year-old and a 5-month-old. My wife and I help her, mostly my wife cause she’s at home most of the time.

But her friend has been a pain for us. I don’t like her. She lives near us and has been friends with my wife for a year. She comes over almost every other day and spends hours. She is senseless and rude and talks loudly.

We have to remind her almost every time that she has to wash her hands before touching children, and the worst part? She sometimes shows up drunk.

She came over 2 days ago and touched my 5-month-old niece without washing her hands, and on top of that, she was drunk!!!

My SIL got angry and asked her to get out of our house. She said that she’s sorry and went to wash her hands, but my SIL grabbed her hand and asked her to leave. I had enough of her as well, so I joined in and asked her to leave.

She was very angry but didn’t say anything and left.

But at night when I was using my wife’s phone, I saw that she texted my wife and said that we were rude and we shouldn’t have insulted her. She is trying to warn my wife that there’s something going on between me and my SIL.

When I saw her text, I asked my wife if she still wants to be friends with this one after what she texted. My wife said she doesn’t know what I’m talking about. I showed her, and after reading it, my wife said that she never expected her friend to say something like this and she’s breaking her friendship with her.

I said it’s necessary because if she didn’t cut her off, I would have divorced her. My wife got angry at me for bringing up divorce and she’s not talking to me after yelling at me for half an hour.

My SIL says that I am wrong for mentioning divorce when it’s her friend’s fault and not my wife’s.

Here’s how people reacted:

You were right to object to this drunk and rude ex-friend touching your niece with dirty hands. You were right to stand up to her. You were right to address this with your wife.

But that isn’t what you’re asking about. You’re asking about whether your wife was justifiable upset with you.

That’s where YTA. She had already said she was going to break off her friendship with the rude woman. There was no need to threaten divorce when she had already agreed. Your wife did nothing wrong and yet you threatened her with divorce, just because you were mad about this friend of hers. The matter was already settled and you decided to make it worse. Your wife was on your side but you wanted to treat her like an enemy. That’s where you went wrong. That’s why she was mad at you.

You need to apologize sincerely to your wife. She is not your enemy. She is your partner. Stop treating her like an enemy.

Far-Studio-6181

Yes, you’re the asshole. Both your wife and your SIL are correct in why. She already was breaking the friendship, but you and your fucking rage boner had to finish your little temper tantrum and threaten divorce. As a husband and father I’m telling you that you sound like a teenager that can’t manage to regulate your emotions. Even still your righteous anger oozes from every word in your post.

Get it the fuck together. You got what you wanted. Take the win without being an asshole about it.

But in this situation go apologize profusely to your wife and thank her for having your back. Even without your asinine threat.

YTA…

Bringing up divorce after your wife had already agreed with you? It’s the same as your wife telling you that is you ever sexually assualt someone she will leave you. It may be true and honest. However there was zero reason to say it except to further hurt your wife. The woman who just lost a friend she thought was an ok person but now realizes isn’t. Instead of a little empathy for the woman you love, you chose to attack her further. That is a shitty way to do things.

No-Shock-2055

NTA. So your wife doesn’t think her drunk, entitled, germ-carrying, freeloading friend is a problem? Let her stew. You and your SIL have had to put up with the wife’s friend for a while now. It’s her turn to sit with some discomfort. Also, you have a right to your boundaries. If that’s a hard boundary for you and you meant it when you said you’d divorce her, then she has a right to know how seriously you’re taking this. Her pouting routing isn’t going to change that.
Zealousideal_Fan1308

You’re justified in your anger with “bitch friend” however, you took that out on your wife, when she already claimed to be on the same team as you. You’re just giving her a reason now to doubt your trust in her. When you express an automatic consideration for divorce if she hadn’t agreed with you already, you absolutely close the door on communicating in a healthy way and have now shut your wife out of being able to express herself and her feelings.

YTA – Not for sticking up for your SIL, but for what you said to your wife. She had already said she was breaking off their friendship. You should have left it at that. To mention divorce because of this? Are you daft?!? Is there something going on with your SIL? You don’t divorce someone over that! If you’re willing to give up on your marriage because of that, you don’t love her. She would be well within her right to divorce you though!
fromhelley

Yta. Not for kicking out the burden disguised as a friend, but for bringing up the divorce.

She had already agreed to end the friendship. You already won this one. There was no reason to get in one last jab!

Also, you should have told your wife many months ago that if she wants to maintain that friendship, she could do so outside the house. The friend is to disruptive to hang out with young children, or even adults!

yo_bored_kitty_zuzu

Yea, I’m just going to sound like a parrot. But you’re wife said she’d end the relationship and then you mentioned the divorce. YTA for that. Not for kicking the friend out. You made it worse.

Your emotions are valid but you allowed your emotions to control you at that moment and said something unnecessary and hurtful.

You need to go apologize to your wife. Communication is very important in a relationship.

WafnaAbroad

Yeah, there’s a lot to unpack here.

NTA for kicking out this friend who rocks up drunk and handles babies without washing, NTA for backing up your SIL.

YTA for bringing up divorce on this. Get a marriage counselor or couples therapist as soon as you can… ’cause now that you’ve opened the door to divorce, just by mentioning it, you’ve caused damage to the relationship and made divorce more likely.

esmithedm

So your wife saw what you showed her, agreed with you, took the exact action you wanted her to take and after all that, you felt the need to beat your chest and pretty much say “you’re lucky you did what I wanted because if you didn’t I would divorce you.”

So essentially you threatened someone who was doing exactly what you wanted of her.

Ya, you’re pretty much a complete asshole. YTA

VileInventor

You just gave your wife an ultimatum of divorce. That’s fucking insane dude. Through no fault of her own you just told her you’d leave her if she didn’t drop someone. That’s a very serious threat, the moment you open the doors of threatening to divorce/break up etc… you open yourself up to it back YTA. Hope this doesn’t blow up in your face. There was 100% better ways to go about this.
ZenZeitgist222

U R an AH!!! WTF… she said she is cutting contact and yet you felt it was necessary to throw in a threat (completely unnecessary) and you chose to throw around DIVORCE!!!! Where is your mind?!!! That is not something to play with unless you mean it… you could catch a huge case of FAAFO doing that! Unnecessary and uncalled for behavior on your part sir!!
CarmenDeeJay

Boomer here. We didn’t generally wash our hands specifically for the purpose of touching a baby. We wash them when they’re dirty. If I’m on my keyboard, and my grandbaby is in her playpen, I’ll pick her up with keyboard fingers and think nothing of it.

Is this a new thing for millennials? I’m genuinely curious.

Sufficient_Exam4033

Firstly the title makes it seem like assault . (I understand that English is not your first language, but it’s hugely misleading) Secondly, You want to divorce your wife because you want her to cut off her friend .. you just straight up jumped onto divorce ??? FML .. you sure you’re not eyeing the sil ???
Fit_Procedure_2288

YTA for mentioning divorce when she already agreed to drop the friend.

“Hey thanks for breaking up with your friend, but just so you know, I would have divorced you if you hadn’t”

Lol bring it up again and you’ll actually be divorced, is my guess.

Bencil_McPrush

Yeah, the “friend” has to go, she’s a viper in the nest.

I would talk to your wife and ask her if she thinks there is something between you and your sil. It’s better to get these things out in the open than to let them fester.

yakkerswasneverhere

NTA for how you reacted to the friend. YTA for threatening divorce when your wife was clearly cutting off the friend. You’re making it like your wife made the friend be a shitty person. That’s just plain wrong and dumb.
Regular_Boot_3540

YTA. What was the point of bringing up divorce? Your wife seemed to be on the same page as you. Were you just flexing your power over her? Quite the asshole move. However, banning the drunk friend is the right choice.
Fine-Virus7585

You were ahead until raised divorce. That like going nuclear at the first sign of conflict.

YTA. UpdateMe

Frankly, you are right to get that woman out of your life, but why did you need to explode your marriage?

Newbosterone

NTA, but threatening divorce borders on it. Even if that’s a non-negotiable dealbreaker, there are better ways to bring it up. It’s difficult to have an non-emotional discussion after you’ve said “or else”.
bplimpton1841

Yes, YTA. If you mention divorce in any context other than talking about the neighbors down the street, your partner is going to forever think that you are already thinking about it.
FantasticVast01

YTA She was already cutting off her friend without being asked. No need to mention divorce at all. Its not something you should throw around just because you are angry
Organic_Security5742

She had said she cut her off then you went and stuck your foot right in your mouth. Never say the D word unless it’s time to sign papers. So yea this makes you TAH.
Electronic-Elk4404

Once someone mentions divorce, your marriage is already dead. Good Job OP! YTA!!! She was already making the choice to drop her. Now you showed your true colors
Inner_Pipe6540

Yta you sound like an abusive partner that says divorce even when she agreed with you about ending a friendship. Take some anger management classes
HoldFastO2

YTA for bringing up divorce. What did that achieve? Your wife already promised to cut her friend loose, so why did you need to threaten her?
IMAWNIT

YTA. You escalated this and it is entirely your fault. Your wife offered a solution and then you threatened her to follow through.
IllTemperedOldWoman

Info: why did you feel it necessary to threaten divorce for something your wife already agreed with you about?
Puzzled_Elderberry_2

That was stupid to bring up divorce. Go apologize for the stupidity that came out of your mouth
404nuha_notfound

NTA. this little friend of your wife would have caused problems between you and your wife
KweenBee1986

NTA for kicking out bitch friend. YTA for mentioning divorce AFTER she agreed with you.
auxilevelry

YTA. You got the good ending and then hard pivoted at the last second for no reason
comomellamo

YTA. You are getting mad at your wife for not reacting to a text she hasn’t read?
not-your-mom-123

Apparently you want a divorce. You said what you meant. You’re a jerk.
Far_Information_9613

YTA. She already was dropping the friend. Why did you create drama?
Mother_Ship_7913

You’re only the AH is you don’t apologize for bringing up divorce
Kerrumz

Why even say that man? You are an asshole for bringing THAT up.
Beachboy442

Wife should support you n safety of children.
berto10101

Never use the “D” word unless you want one.

Conclusion

The original poster (OP) is clearly distressed by a friend’s dangerous and disrespectful behavior toward their family, leading to a firm confrontation where the friend was asked to leave. However, the conflict escalated when the OP introduced the threat of divorce to enforce their boundary regarding the friendship, causing significant marital strain despite the friend’s unacceptable actions.

Was the OP justified in using the threat of divorce to demand the immediate termination of his wife’s friendship, or did this ultimatum unfairly pressure his wife and undermine their marital trust regarding an issue primarily caused by the friend? This situation forces a balance between protecting the household from a hazard and respecting the autonomy within the marriage.
