This guy has a GF but i think he likes me cuz he IMs me and calls me everyday.He still cares about his GF,tho!

just ignore him...he may like you, but if his gf finds out, you dont want it to turn ugly like you are to blame. also, dont get involved with this guy if he is taken, its gonna make u seem kinda slutty...maybe talk to him about it? maybe he just likes u as a friend and would like to get to know u better
