During Amy’s visit, the OP noticed Charles making several comments directed at her sister that were highly inappropriate, including calling her “so hot” and remarking on her developing body. When confronted, Charles became defensive, accused the OP of being “paranoid,” and insisted he was just being “nice.” The OP responded by immediately ending the engagement and moving out, leaving her unsure if her reaction was too extreme.

I (20F) am in a tough situation, and I’m not sure if I’m overreacting, so I need some outside perspectives.
I’ve been with my fiancé, Charles (35M), for about two years, and everything seemed fine until recently. A few weeks ago, my 14-year-old sister, Amy, came to stay with us for just a few days while our parents were out of town.
During her stay, I started noticing some really unsettling things.
At first, I thought I was imagining it, but Charles started making comments that made me feel incredibly uncomfortable. He would call her “so hot” and would say things like, “You’re going to turn heads when you’re older,” and “You’ve got such a body on you already.” The worst part was when he said, “I’d be jealous if I were your boyfriend, every guy will be looking at you soon.”
I tried to ignore it at first, but it kept happening, and I began to feel sick to my stomach. Then, one evening, I overheard him telling a friend on the phone, “Amy’s got that look now… it’s like she’s starting to bloom.” It was honestly one of the creepiest things I’ve ever heard.
I felt like I was losing my mind, and I just knew I couldn’t stay in that relationship anymore.
I confronted him about his behavior, and he immediately got defensive. He denied it and said I was being “paranoid” and that I should trust him. He insisted that he was just being “nice” and that I was overreacting.
I didn’t care. I packed my things, broke off the engagement, and moved back in with my parents. Now, my friends and some family members are telling me I overreacted. They say I should’ve “talked it out” with him first, but I don’t see how that would’ve changed anything.
So, AITA for breaking up with my fiancé because of his creepy comments toward my little sister?
Conclusion
The OP is now facing external doubt from friends and family who suggest she should have discussed the matter further before ending the engagement. The central conflict remains between the OP’s strong, protective reaction to what she perceived as deeply inappropriate behavior and the expectation from others that a less drastic conflict resolution method should have been attempted.
The core question for debate is whether the severity and nature of the fiancé’s comments regarding a minor justified an immediate termination of the engagement, or if the OP was too quick to dismiss the relationship without pursuing further mediation or communication efforts.
Here’s how people reacted:
If he has some money and you actually like him, the problem for you is finding another like him that wants to marry you. If you bail, He will 100% replace you with another 20 yr old who will happily deal with inappropriate comments every once in awhile if it means she gets wifed up.
Something wrong with your family and friends if they want you to talk it out and negate every creepy think he’s said to your sister.
BTW how did this affect your sister?
But yeah there’s 100% chance that guy’s a pedophile and you should probably report him to somebody for being a potential threat to children
It’s possible you’ve just gotten too old recently and its time for a reboot. New talent.
He’s a pedo in the making.
NTA
Btw, find someone closer to your own age next time, that guy was a groomer.
From his perspective, you’re the same age.
