I destroy my relationships by acting out

Recently I met a great man and the relationship was moving along nicely although I thought perhaps a bit too fast. Only on the third morning that we were together I treated him as if he was a virtual stranger and in a way that said to him get out of my house now I have things to do. I did not make coffee, did not give him a towel for a shower and pointed him to the door and did not kiss him when he left. I have no idea why I acted this way. When I think back to the whole incident I barely remember it but I do remember being cold this way. It is not the way that I normally act with someone that I am interested in. It has had irreversible consequences as he has broken it off and won't contact me. He says that our behaviour, actions, and communications is incompatable. I do not blame him for this--as it is what he feels. I would also have felt very badly if it had been done to me.

Is there a medical condition which explains this kind of unexplained acting out which is kind of an out of control behaviour which gives a sense of me acting out in ways that I don't really mean and it is as though I am watching a movie of myself doing something and yet it is not really normally how I behave and in this case it has had dire consequences? It has happened before a few times and in some cases it has had dire consequences and in others it may or may not have.

Thanks
