What is his deal...........?

i have been talking to this guy for about 6 weeks now. he says he likes me and feels something for me but im not sure if i trust him. it jsut always seems like guys are all the same. my friends are tellin me oh hes just b-s-in u, guys will say anything to get some, stuff like that. but i told him if he only wants a call to tell me and thats straight. and he says he doesnt. im startin to develop feelings for him to but am tryin not to set myself up for heartbreak here. sometimes he'll call and we will talk forever about anything and he comes over and just hangs out and doesnt mention . that doesnt seem like he is just lookin for some nooky. and how long would he play around with me if that is all he wanted. its been 6 weeks. wouldnt he have quit it by now. if i talk to another guy he gets a little jealous and i asked him why and he says he doesnt know but he lieks me and it kinda makes him jealous. so jusst what do u think is goin on here. does he like me or is he just tryin to get laid for a while.
