Please help me out here.

Can anyone help me out here?? My ex is still having sex with HIS ex. She has a boyfriend who is MY friend, and he refuses to believe anybody that she is doing anything of the sort(because she tells him that she loves him)! My ex has told people that her and him still have sex. We are on spring break, and her boyfriend is gone to florida. Well guess whos car is sitting in front of her house>(MY EX'S) If I took a picture of his car in front of her house, will her boyfriend believe me or not? She broke up with my ex (numerous times) because he doesnt treat her very good! So why is my ex still having sex with her when she has a boyfriend?? He tells me he "loves" her, but everytime they hang out(whenever her boyfriend isnt around)they have sex!! I told my ex that he is confused about the difference between love and lust, and he gets really angry! My ex jumped on this little girl(she was 14 he was 17 at the time)while she was in a relationship(imagine that) I was good friends with that guy too. She was having sex with him and my ex for weeks after she broke up. Because she still loved her ex, but she told me she really didnt even like my ex at the time! The only reason she ended up picking my ex was because I told her everything her ex talked about her. (nothing good> he just wanted the sex>and that sucked too) So when I told him that shes been having sex with the both of them, he said F**k this and didnt want anything more to do with her. Why is my ex so stubborn? Him and I liked each other for many years. We started dating 3 years after, but we never had sex(all the way) we did a lot of stuff, but my virginity is very important to me. Him and this girl had sex the 2nd night (they barely knew each other) Is it just the sex with her that he loves? Did he even love me like he says he did, even though we didnt have a relationship like that? Is he just running back to her because of the sex? Or does he think that because she is having sex with him shes leading him on to think that she wants him back? Him and I are hanging out tomorrow. I dont know what we should do. I dont even know what to talk about. Any advice is greatly appreciated!!

Ok, that was a bit complicated to fallow with all those's ex's. But from what I understand, you like this guy but he is having a sexual relationship with some else. If he loves you he wouldn't be having sex with some else! That wouldn't be very respectful or loving of him now would it? As for the reasons he continues to see this other person, only he can tell you. I think you need to get your relationship with him cleared up. Are you together? Are you just friends? If your just friends and you don't have feelings for him then you need to accept that his personal love-sex relationships are not up to you to choose. You just got to be a good friend and do what you think is right. If you do have feelings for him then you have to adress them and find out how he feels about you. The way you describe him though isn't very promising since he seems to have a tendency to lie and not be very caring and supportive. Sounds like you guys need to have a good talk and get things cleared up so you know where you stand. And as for your friend who doesn't want to beleive that his partner is cheating on him despite that people have told him, a picture would not convince him because he has to want to confront his girlfriend about her actions.
