So, she told me that her ex wants us to break up. She says he is a friend, and she says he is her everything as a best friend, and I am her everything as a boyfriend. She also says he cares about her, and wants the best for her.

So I told her if that's the case, then she should go be with him. She was crying and we decided to talk tomorrow, and she begged me not to break up with her, so I am thinking maybe she does love me. She also said he always wants her to break up with the boyfriends she has had, and she knows him better than she knows me.

What should I do? Should I break up with her, or not?

Yea break up with her . She doesn't know what she wants she seems like she just wants the fact she can call Someone her boyfriend

Talaniman Rule - Leave people alone who still have exes in there lives.

He has way too much influence on her.
