Please say I'm not alone in this. My boyfriend had one girlfriend before me. She took his virginity and he calls me the same things he called her. She took all of his firsts and I didn't get a single one. He has all of my firsts. And I hate myself for this but I think about the two of them too much. And to add on to that, his ex-girlfriend was a close friend so I know about everything they did.  How am I supposed to handle this? After 11 months it's only gotten worse. It eats at me daily And I know it eats at him too. I feel as if I'm in constant competition with her even bough she's gone. What do I do...
