She brought out the line "it ain't broke don't fix" to describe the relationship she is currently in. Hmmmmm....
As much confusion as she is presenting with her feelings between you and her current BF, it sounds like she doesn't speak so highly of her current BF at ALL. In all honestly bro, if this is the case, if she would break up with this guy and not feel any different, then in MY opinion, there is something "broken" in that relationship. If there aren't any strong feelings, that sounds like a problem in itself. Has she presented much feelings towards this guy she's with at all?
