Relationship advice please..?

Ok, so I have been off and on talking to this guy for 9 months now. I have crazy feelings for him and he says he feels the same for me. However, every now and then when things have been going so good he will starte to say **** like ';call you other boys'; or ';who were you with last night'; and i LITERALLY do nothing but work and come home and most that time is spent talking to him. Today i was supposed to call him abck and i fell asleep and when i woke up i called him. Now he is saying that he doesnt believe me and that i was probably talking to someone else on the phone. I dont know where it comes from or why he does it, but i really care about him and dont wanna give up. You all think this could change or am i just setting myself up for major hurt in the end? He like says this stuff but still wants me, still talks to me..everything. HELP!Relationship advice please..?
He is really insecure and if you get into a relationship, no doubt he will turn out to be really possessive and the accusations will get worse. I'd say it's not worth it.Relationship advice please..?
