Search Results: ex bothering me

Tbh I might just be overthinking because my last relationship ended very badly, my ex was constantly cheating on me so i definitely developed some trust issues after that

My girlfriend has a male friend that she’s known since kindergarten. While I’ve only known her for a year maybe, we’ve only been together 2 months

He’s one of her best friends which never bothered me until today she told me that there was a time they “fucked around”
they didn’t fuck but she said they made out and he was grabbing her boobs. She only told me about that one time but there could of been other times they did stuff for all I know

I keep trying to tell myself that he’s dating one of her best friends now, and if they really were into each other like that then they would of been together by now. And i appreciate the fact that she was honest with me, if she was really hiding something she wouldn’t of said anything.

But since they did that, that means there’s obviously attraction between them.
I do trust her, I believe her when she says she wouldn’t do what my ex did to me, but I just can’t help it bothering me.

I would never be the controlling type to tell her that she can’t be friends with the dude tho. Especially since they’ve known each other way longer than she’s known me.

I just don’t know if I’m overreacting or if it’s normal to feel this way
