How do you deal with living in the same house after a breakup?

I was in a 4 year relationship as of a day n a half ago. Engaged two. We never set a date. He bought the house, Supposedly for our future. I gave up my place and moved into the house. We have been living together a little over two years. We had an argument 1 day ago, and told me he is done with this relationship. This last argument lit the fuse on the bomb and it exploded. Like any other relationship we have had our problems, but I was under the impression that we were going to work things out. I came back from visiting my family for the Christmas holiday. Then we were getting ready to head out of town again. A day n a half ago we got in a little argument and he said that he was done with the relationship. He feels like He does not make me happy, nor is he no longer happy. Prior to that we had been sleeping in different rooms. This break –up to me came out of nowhere….we were suppose to be working things out..how is this working things out? I asked him was he having a mid life crisis. He said maybe, he just knows what he does not want for 2009. Later on that night he came to me and gave me a hug and we said that he cared for me. He also gave me a massage like no other and did intimate stuff to me without intercourse. I told him that he was sending mixed message. I will have to accept the breakup. I got a Storage today and trying to cope the best I can. He indicates that I can stay until I get myself together/place/relocation of job equipment. This resident no longer feels like HOME. It is awkward. I am trying to get the hell out fast as I can!
