Two minute break-up

Well, Heath and I broke up for a whole two and half minutes. I blew up because he kept telling me I was wrong about how I couldn't find a cable/satellite TV deal that would save me money. I think I would know since I spent the whole day looking. He has this habit of always telling me I am wrong. Last night he told me I was wrong and that the court could order my ex to pay back the money. He figured a few days in jail would make my ex pay me back-ha! He definitely hasn't met my ex. I have looked into this-spent weeks agonizing over it and in the state of Georgia, the court will order him to pay, but they don't do anything that helps with collecting the money-technically he doesn't have to pay. Nothing would make me happier than to get my ex to pay me back, but the time and money it is going to take is something I don't have. Well, back to the break-up tonight. I told him I didn't like how he was always telling me I am wrong and screamed for him to "get out." He grabbed his computer cord (which he always leaves over here) and told me I could keep everything else. He told me that he didn't like it when I raised my voice. I told him to sit back down. We agree we have a communication problem-I don't exactly know how to fix it. I apologized for raising my voice. He said he would try working on telling me that I am wrong-of course in the conversation he again kept telling me that I am wrong. A few days ago he tried to tell me that I was wrong about Resident Physician work hour rules(I think I would be the expert in this seeing that I have to go by them), so I don't think this habit is going to be so easy to break. I do think we would be able to communicate better if I didn't constantly have him telling me that I am wrong. We got in an argument about a medical issue and since I knew I was right and he kept telling me I was wrong-I sent him an e-mail with a link to my online medical textbook to prove I was right. Now I get that I don't know every medical answer, but I know enough to have a medical degree and I think perhaps accepting somethings I say without arguing about it. I don't disagree about computer things, although sometimes I would love to-I think he must think I am an idiot in the computer department, but considering I was writing my own programs at the age of 7 and did 99% of the technical support for my labs, I can do more that Facebook and e-mail. I don't know how this is going to turn out-I am not ready to call it quits, but I am getting tired.
