Dealing with the ex files

I have been with my boyfriend for two years and I really love him. He is my first serious r'ship. I’m 19 and he’s 20. He was really stupid enough to tell me and my mum all about his past relationships. And I mean everything about them - all the sexual details too! In total I’m his 12th girlfriend. I feel like I am just a number. I know everything about all of them and I hate that. Not all his relationships were serious, but one was. I can't deal with that. What should I do? Anon

Ah, yes. The ex files. Everyone has them and you can’t avoid them being opened up at some stage in any relationship. As icky as it is to hear about your boy being luvved up with someone else, we all have a history and it’s part of who we are now. The best thing to do is accept your boyfriend’s past relationships and move on with yours. There’s absolutely no good that comes from becoming a green-eyed monster and stressing out about girls who are long gone. Although, seriously, he could’ve spared you the sex details and waited for your Mum to leave the room!
