My boyfriend and I have been together for about 9 months, I lost my virginity to him, everything had been going really good. There's only one problem, his ex girl friend. They dated about four years ago, they had sex as well and only dated about four months. They have been friends off and on since then and he says they haven't touched each other since. She is always texting him and calling him asking him to come over to her house, and to go to the bars with her. I'm only 19 he's 22 so I can't drink. And a lot of the time he's with me so he tells her no. She throws an absolute fit about it every time, and always threatens to "not be his friend." Last weekend they got in a fight and were ing through text messages and I am not pround of it but I read through them. She talked crap about me and he didn't defend me. He also said he's in the doghouse a lot because he picks her over me, which I don't think has happened. He tells me he never would. Basically my question is, should I be worried about her?

If he can't end it with his ex, you should end it with him.

You should be worried and upset with your boyfriend.
He is responding to her, he is keeping up the conversation.
You need to end it with him.
