I need advice about a guy .. both guys and girls please!!!!!?

So to make a very long story short, this older co-worker of mine who goes to college 3 hours away and is 21 (i'm 17) flirts with me and acts interested when he comes home and visits the job. he says he wants me to come visit him and party you know, but then once he goes back to school i don't hear from him at all. hes also come home before but not even told me he was here! last time i saw him he was flirting .. sweet talking you know but then tells me he kinda has a gf at school and shows me a text message from her! i dont know what this guy wants or feels and i dunno if i should try and keep in contact with him ... HELPPP!I need advice about a guy .. both guys and girls please!!!!!?
What does he mean when he says that he ';kinda'; has a girlfriend when he knows very well that he does? Then he flashes you a text from her. That's pretty rude! This guy is leading a double life; one at home and one at school. The only thing he wants from you is someone who he can string along and use as a diversion when he is away from school. That is when feels up to letting you know when he's returned home. Don't you kinda feel that he is using you and he is kinda feeding you a load of bull with all his bogus sweet talk and playing with you like you're some kind of a toy? He has no real feelings for you so don't even try to maintain contact with this clown as you will always be soon forgotten once he has gone back to where ever and what ever is holding his interest for the moment.I need advice about a guy .. both guys and girls please!!!!!?
Forget this guy he just wants to have a girl at school and be with you also. He's a user!
Well you are 17 and he is 21 and he is in collage there is alot of things he could be doing there that you dont want to know about... I think you should maybe find someone who cares for you and treat you as you would treat them.. I know you really like this guy but if has the nerve to come in and cant pick up the phone and call you then he is not worth it. you can find someone alot better... GOOD LUCK
