Hanging with a guy but he has a girfriend (things aren't good between them)?

don't hang out with guys who have girlfriends. it makes you look bad. the guy needs to pick. yes, talk to him and ask him what he expects from his friendship with you. are you just friends, make it clear from the beginning. if you have feelings for him, i would suggest you not be alone with him anymore, because he does have a gf, and if he was your bf, i'm sure you would want other girls to respect that.
