Oak- what are you stupid? That guy wants to fuck your girlfriend, no strait guy would kiss on a chick and then hang out with her unless he wanted to wet his dick in her! You know the saying "In vino veritas", if he kissed her when he was wasted, it means he wants to do that and more to her, and if she is "hanging out" with him, then she wants to do the same. My advice is to beat him into a coma or if you arent able to by yourself, get some buddies to help you or use a baseball bat and then dump that fuckin whore. End of story.
