He is too jealous, what do I do?

My boyfriend and I have been dating for about nine months. All we do is argue and that is because of his jealousy and ever possessive attitude. He dictates and expects me to do everything he says. He suspects I’m dating every dick and harry. I love him but those things he does drive me crazy. All I can think of right now is to break up with him but I love him. Please, help!!!!!!!!!!!!! What do I do? What we have is a platonic relationship. He doesn’t even trust me.
