This is gonna be a bit long and consisting of many questions, so i request the reader(s) to be patient. So I’m 17 and my girlfriend’s 15. This is my very first relationship and her 16th relationship. She still talks to most of her exes, most of who want her back. And that bothers me. A lot. Whenever she brings up a topic regarding her exes like this ex wants her back but she’s like fuck off and stuff but that really gets me down. I know she doesn’t flirt with them and stuff, but it still bothers me. One of her exes is very close to her, they call each other “best friends” and hang out very often, rather they used to. We’ve been in this relationship for 10 months now and last month she told me that a few months ago, when we were having a fight, not a major one, but it really got to her and she was talking to her best friend(the ex) about it and she broke down while telling him and he kissed her. She tells me that it didn’t mean anything, but thing is, they still hung out together up until this month when he started sending her love notes and stuff and she got her mom to tell him to stay the fuck away from her. And this broke my heart. I kept telling her it’s okay, it’s probably me who pushed her to this and stuff, but it killed me on the inside, I cried and cried and cried, even in front of my friends in school I broke down, I’m still not over it.It keeps haunting me again and again. She’s very attractive and she loves me a lot, she’s told her parents about me and she’s even ready to lose her virginity to me. I’m fat, and very unattractive, but I love her dearly and do not want to lose her. That being said, it still kills me on the inside every time any topic about her ex comes up. And I do not want to tell her about it because, she might get offended and upset, and extremely sad. I do not know what to do now. Any kind of advice would be appreciated. Thank you.
