Due to this shift, the user can no longer bring themselves to use the familiar term “mum,” finding it inappropriate given the circumstances of the new child’s father being younger than them. The mother has reacted negatively to this change in address, making critical remarks and complaining about the user to other family members, leading the user to consider completely severing contact for a period.

Title is self explanatory I guess. My mother is having a child with her boyfriend who is 4 years younger than me. He’s 22 and she’s 47. As a result, I’ve had a hard time viewing her as a “mother”, and she feels more like a fellow peer now.
I can’t bring myself to call her “mum” anymore, it just feels so fucking gross to call her that when she’s having another child with someone who’s younger than me. She of course is furious with this, and has began making stupid remarks about the way I’ve started addressing her, and badmouthing me to family members among other things.
But I don’t care. I’ve always been uncomfortable with their relationship but tried to blank it out as I was only visiting her like once a month. But HOLY SHIT, I can’t stand being around either of them at this stage and I feel like I need to sever ties for the time being.
Anyway that’s my dumbass post. Fucking hell man, why was it so hard for her to stay within her age range? How the fuck does she not see how wierd this shit is? Fucking Boggles my mind!
Conclusion
The user is experiencing a major identity crisis regarding their relationship with their mother, rooted in the age difference between the mother and her new partner, which has made the established familial role feel invalid to the user. The mother, in turn, is reacting defensively to the perceived disrespect regarding their address and the user’s discomfort.
The central conflict is whether the user is justified in altering their mode of address and distancing themselves due to personal discomfort with the mother’s lifestyle choices, versus the mother’s expectation that the user maintain traditional familial roles regardless of the unconventional situation. Is the user’s need for boundaries more important than maintaining superficial familial harmony?
Here’s how people reacted:
suppose you made a decision that she felt was bad. How would you feel as suddenly she referred to you by your name, refusing to call you daughter.
That your mother has issues, and that she’s in for a difficult time, is beyond question. With the fact they were her decision, and not yours is immutable.
You’re just making up an excuse to treat her disrespectfully and thinking yourself righteous for doing so. You want to look down on her for being a cougar, own it, but don’t think yourself virtuous for being a dick to her.
I told him there’s no fucking way I’m hanging out with him and her. I felt sorry for her at first until it became apparent by the things she said.
He bought her a brand new car, paid for her university, up until she dumped him to date his friend—a very rich and older guy that was in his 70’s.
My dad’s wife is 4 years older than me. They’re happy. I’m happy for them. Although she was in her 30s when they got together, so more mature.
You’re about the age as my sister was when my dad got remarried. She was a brat about it too. Grow up. YTA.
It’s funny to me, kids seem to only call their parents by their actual names when there is an actual or perceived problem in the kids eyes. Like you’re trying to gain some power by changing what you call her now. I don’t think it makes you an asshole, but also, her adult actions don’t make her any less your parent.
And beware the people telling you to have ‘sympathy’ – once she’s a 50 yr old single mom with a toddler, sympathy will get your Next Gen Sibling dumped on YOU to raise faster than you can blink!
But I would be more concerned that your mother was so stupid.
Either she was so stupid that she didn’t understand birth control and how it works
OR she was too stupid to realize she is going to be raising a child alone at nearly fifty years old.
Either way, have some sympathy.
Your mother is stupid.
NTAH.
Your mom is more worried you’re calling her by her name than the fact that she’s with a 22 year old?
NTA that’s just uncomfortably weird
Calling her by her name aside, you need to distance yourself unless you want to be pulled in for CONSTANT help and babysitting.
Shes your mother. Who tf cares who she fucks and has kids with.
Youre a brat who needs a hard lesson is respect
