Lately my girlfriend has been talking to her ex a lot. He phones frequently at late times, and has showed up at her work a few times with coffee. This guy used to abuse her and has even raped her. I'm not usually a "clingy" guy but this is bothering me quite a bit. I have no clue why she is even talking to this creep... What should I do? I don't want to bring it up and come off as a clingy needy guy. We've been together for a few months and I really care about her.
