SHOULD i STAY??? Or GO????

First of all let me start off by saying i've known this guy for like 4 years.... we've liked each other ever since but we never got serious bcuz he always lets someone get in the way... we've talked on and off but after the last time he started lying to me about other gurls and know i dont trust him!!! it seems like he knows he wants to be with me >>he told me>>but he's not ready to settle down yet...he wants to go and mess with all these gurls and whenever he's ready he thinnks im going to be there but im not...i pushed him away and ended our friendship even tho it hurts me i thought i as going to be with this boy sooner or later but i guess not.. i hang out with his cousins there my bestfriends and he's always around i dont know how to act...but i just cant take it nomore what do i do.....
