Blended families only work when everyone gets a say, but not every parent wants to share the steering wheel.

So when one father’s fiancée questioned why his teenaged son never hung out with friends after moving schools, he shut her down instead of hearing her out.

It set the stage for a deeper conflict over both of their roles in the relationship.

Keep reading for the full story.

AITA For Telling my fiancée to mind her business about my son’s social life?

I (41M) have a 15-year-old son. Me and his mom broke up when he was 8, and I’ve been dating my fiancée for almost 4 years.

I have primary custody of him, and I moved to a different city before he started 9th grade. So he goes to school in my city.

He’s in 10th grade now.

This dad recognizes it’s a big transition, but has full faith his son can make the best of it.

Obviously moving high schools is tough, but I didn’t think it’d be too bad for my son.

I think he’s pretty social, and he plays sports for the school and is in a few clubs.

His fiancé, however, saw things differently.

Recently, my fiancée has been bothering me about how my son doesn’t go out with friends often (or at all, she says), and I’ve asked him about it and he says it’s not a big deal.

So that’s that.

But she won’t drop the topic, because she thinks it’s not “healthy” for him.

So finally he lost his cool on her and it only made things worse.

Yesterday, my fiancée brought up the topic again, and I told her maybe she should mind her business on my kid’s social life.

She called me a jerk and now she is giving me the cold shoulder.

AITA? I don’t think I am because I have repeatedly told her that it’s not a problem.

This father’s reaction makes him seem a bit more defensive than protective.

What did Reddit think?

This father might want to choose his words a little more carefully.

Maybe instead of being annoyed, he should be grateful his fiancé is taking an interest in his son.

Maybe it’s possible his fiancé notices something he doesn’t.

This commenter agrees that it can be hard to tell with some teenagers.

In the end, this father wasn’t wrong to want to protect his son, but he was wrong for shutting out the person trying to help him do it.

If he wants this relationship to last, he’ll need to learn that “mind your business” doesn’t work in a shared household.
