If I move out will we break up?

We have been dating for a year and a half. I moved in about a year ago, and at first it was pure bliss. But then everything went down hill. He became so needy, i did all the laundry, cooked 2 meals a day, dishes, everything in the house, i felt like betty fricken crocker house maker! no offense to anyone but that is not how i imagined my life. Anyway it was not only that, we fight about everything, i mean everything. Its like if one of us isn't annoyed the other one is. Im not saying I don't love him, I do so very much and it is breaking my heart to see us so miserable. Anyway, we have been talking about these issues and have finally came to the conclusion that I should move out for a couple months and see how that goes. We would still be dating but we both agree that we moved in together way too soon and need to reevaluate our lives and get a little individualism back. If I move out though, I am affraid we are doomed to break up, and that kills me. What should I do? And where is our relationship going?
