Does he like me or is he just messin w/ me?

ok so i kno this guy joey. i went out w/ him for like 2weeks. he wouldnt tlk to me in skol but on myspace all the time. he asked out my bestfriend the day b4 me. and then how we broke up was cuz i found out he had a gf whn he askd me out and still did. then like 2 days after he told me it was a lie and tht he wantd to go bck out w/ me but i couldnt tell. so cuz i liked him i sed yes thn we decided to just b friends and now he keeps tryin to tlk to me and the other nite we tlkd for 2 hrs on myspace and 3 hrs on the fone. he acted like he truly caredand told me he still like me and tried to convince me to brake up w/ my bf for him. and sed no so he sed tht we should be freinds w/ benifts... i dont kno wht to do?
