What just happened?

I met a man a year ago. I will shortcut the charm , spoiling me rotten, telling me how gorgeous I was etc etc. He encouraged me to rent out my house and move in with him, also rejecting a well paid job abroad (which I did because this was IT). Shortly after I moved in, he began criticising my appearance, telling me he preferred blondes (which I am not) ,,,, and then the real stuff began. He is obsessively tidy and I had to start following his list of rules . Nothing I did was ever right, I used too much washing up liquid, I did not peg clothes out with the right pegs or in the wrong place. He kept saying I had not learned things in life that I should know. Every time I learned a new set of rules, they would change. I have a very demanding job, and as to start with he was working at home, he said he was happy to take care of domestics. When he became busier, my work suffered because I was trying to fit in all of the things I had to do his way, and I didn't have the time. But it did not make him happy. I arranged lots of little treats and surprises for his birthday, took him away for two days, but he barely spoke. When I challenged him about it, his eyes were cold and he said that he wasn't going to talk to me because I had just assaulted him! The last three months, he just withdrew emotionally which made me very anxious as I had just rented my house out again, then last week, I asked him again what was the problem. He just said that his dream had been shattered, that he did not love me and he wanted me to go. I began to pack a bag to go to a friend's house, I was in a terrible state, and he just said he needed to go to work. And did! He sent me a message to say that he had tried to live with my faults, but it was unsustainable and he had become aware that I was not a long term viable proposition! Who speaks like that?!

This is garbled because I am sleeping at a friend's house, he does not even know where I am, and I have been unable to eat or sleep properly. I am angry with myself, because I did see signs that made me uncomfortable, I recognised that I was losing myself, I felt uncomfortable when my friends and family phoned, because he showed irritation by clattering around and talking to himself loudly. I changed so many things .... And they were all the things that he said he loved at the start. My spontaneity, humour etc ... Nothing was good enough. He had a string of exes that he is still friendly with, which also made me feel a bit insecure. But I can't believe how much he changed, and he has left Me with the feeling that I am unlovable, useless .... How could he care so little as to not even wonder if I am ok? He sent an email with a list of things that I took that need to go back, and a list of things that he has packed up for collection ... That is it.

I am in a very bad way, and despite this being all muddled, would appreciate any thoughts to help get through this.
