You're Hot then your Cold?

Ok sooo... me and my boyfriend have been together for almost 7 years. High school sweet hearts a little one and all that jazz. We just moved in together I would say about 4 months ago. For some reason we argue a lot more than usual and then we make up. We fight (hard) and we forgive. As you can imagine this is getting very tiresome. What should I do? How can I resolve all the fighting? He is extremely stubborn and he says im a sarcastic B**** but I feel all I do is retaliate to his madness which he provokes... Im tired and need some advice. How can we make this work?
