The core conflict has arisen from Daniel’s stepmother, Valerie, who has become increasingly insistent that the OP and Daniel are emotionally or even distantly related, referring to them as “the twins” and presenting a fabricated family tree. When the OP expressed discomfort, Daniel dismissed her concerns, stating she was overthinking Valerie’s behavior. The OP is now deeply unsettled and questioning whether to proceed with the wedding due to this toxic dynamic.

So, I (23F) am engaged to my fiancé, Daniel (24M). He’s the son of a very wealthy businessman, and to be honest, I come from a much more humble background. We met a few years ago at a mutual friend’s party and hit it off immediately.
We have a ton in common—same sense of humor, similar values, we’re both super family-oriented, and we have the same weird taste in music. We even share similar quirks and habits that make us seem like we’ve known each other forever.
Basically, we just click.
Here’s where the problem starts. Daniel’s father remarried a few years ago to a woman named Valerie. She’s in her mid-40s and, well, let’s just say she’s not the nicest person. She’s always been kind of cold to me, but I didn’t think much of it.
A little passive-aggressive here and there, but nothing crazy.
However, over the last few months, things have started getting out of hand. Valerie started making these strange comments, usually when we’re alone or in private settings. She has started implying that Daniel and I are too close for fiancés.
The first time she said it, I laughed it off, thinking it was some weird joke. But then it kept happening. She started pushing the idea that Daniel and I are not just fiancé and fiancée, but rather brother and sister in some kind of spiritual or emotional sense.
She kept saying things like, “It’s just like the way real siblings can talk for hours about nothing” or “You two look so much alike, I’m surprised you haven’t figured out you’re actually related.”
I thought she was just being bizarre, but it kept escalating. At one point, she showed up at one of our family gatherings with this family tree thing that supposedly proves Daniel and I could be distant cousins.
The family laughed it off, but the whole thing left me feeling unsettled. I’m not sure why she’s so obsessed with this narrative, but she even started calling us “the twins” in front of other people, which made me feel super uncomfortable.
I’ve talked to Daniel about it a few times, and he says I’m overthinking it, that Valerie is just trying to get under my skin. But at this point, I’m not so sure. I feel like Valerie is intentionally trying to paint us as siblings to make me feel uncomfortable and to undermine our relationship.
And it’s really starting to mess with my head.
We’re supposed to get married in a few months, but now I’m seriously considering calling it off. I don’t know if I can marry into a family that has this kind of weird, toxic dynamic.
I don’t want to feel like a part of this twisted narrative that’s being forced on us. Daniel says I’m letting Valerie win by even thinking about this, but it’s messing with my head so much that I don’t know if I can go through with it.
So, AITA for thinking about calling off my wedding because of Valerie’s insistence that Daniel and I are siblings? Should I just brush it off like Daniel wants, or is this a sign that something deeper is wrong here?
Conclusion
The OP is in a difficult position, torn between trusting her fiancé’s assurance that the stepmother’s behavior is merely an attempt to provoke her, and her own strong feelings that Valerie is intentionally undermining the romantic nature of her relationship with Daniel. The emotional toll of constantly defending her engagement against this strange narrative is severely testing her commitment.
The central question remains whether the OP should dismiss Valerie’s actions as insignificant interference, as Daniel suggests, or if this behavior represents a fundamental, unacceptable issue within her future in-law family structure. Is this behavior a red flag serious enough to warrant canceling a wedding?
Here’s how people reacted:
1) Daniel can speak to his stepmother and tell her that her obsession with trying to insist you all are siblings is creepy, inappropriate, and not funny. Then set a hard boundary that if she brings it up you two will call it out as “disgusting and creepy” then immediately leave. You two then need to present a united front every single time it happens.
2) You can speak to her and communicate the same thing if you are comfortable doing it yourself.
3) Daniel lets his dad and stepmother know that you will be going LC or NC because the “jokes” about being siblings are hurtful and inappropriate.
This is an opportunity for you and your future husband to work together as a team to solve a problem.
here’s the thing: she is consistently making you uncomfortable *on purpose* and no one is doing anything to stand up for you and put a stop to it. It doesn’t even really matter what exactly she’s doing, you’ve expressed multiple times that you’re uncomfortable and want her to stop and yet everyone in this family, your fiance included, are happy to allow her to continue to poke at you. Why is that? Why are they all fine with letting her make you uncomfortable and why is it that when you talk to your fiance about it he brushes you off? I wouldn’t want to marry into this kind of dynamic either
This shouldn’t be a big deal, but it does require going outside your comfort zone to confront her. At the end of the day, is Daniel worth fighting this battle for?
“Oh *Valerie.* I know that you have a weird fetish for watching incest porn. Daniel’s dad has told me – and if it’s OK with him then who am I to judge? But honestly, it’s not my bag. You’ll have to find someone else to watch your set of illegal films with, as I can’t imagine they’d do anything for me.” Then leave. Also, deny everything if questioned, but say you’ve been worried about Valerie’s constant suggestions that you and Daniel are related for sone time, and to wonder if she could do with some professional assistance.
Fight fire with petrol.
While I understand your concerns, if you love him, marry him. Don’t let the witch break you up. And stand up for yourself! Tell her to cut the crap and stop making these comments at your expense. You don’t find it funny and she needs to stop. Daniel needs to tell her to shut up and encourage his dad to leave you alone. If you stand up for yourself and Daniel doesn’t back you, then you have bigger problems.
If she constantly tries to get under your skin, your partner should care about that. He should have your back.
“Should I just brush it off like Daniel wants, or is this a sign that something deeper is wrong here?”
It seems there is something wrong with your partner’s allegiance to you. Maybe this is just a phase that Valerie is going through. But maybe this is a preview of what your life is going to be like, if you don’t set clear boundaries right now.
If you can let this woman’s behavior make you reconsider marrying him, I don’t think you’re ready to be his wife. It is incredibly sad that this troll and bitch of a woman has this type of influence on you.
You’re a threat to her cash cow. Can you really not see this?
There are so many ways to handle this. Tell her loudly she’s letting her sibling kink run too wild.Tell her yes, you’re soul mates, and you’re surprised that she and her husband are still together given that they have so little in common. Ignore her. Go low contact. Lots of options better than calling off the wedding.
My husband and I finish each others sentences and have since day 1. His sister and I favor. We are not related and if someone thinks we are and insist on it, I’d shake my head and live my life.
This woman is clearly trying to break you two up. Probably for inheritance.
Play her game instead of letting her get to you….
“FIL I didn’t know you slept with my mother”
“SMIL are you trying to get us to break up so your daughter has a real chance at a incestous relationship with fiance”
“What perverted environment did you grow up in to think this is normal talk”
Everyone knows she sounds like an idiot so let it go until she does something even your in-laws can’t handle.
Does your fiancée’s father hear this? What does he say about his supposed daughter?
On the other hand, if you’re considering calling off the wedding (for whatever reason) maybe you two shouldn’t get married.
