Husband hides things.. Any wise insight ?

We were separated. I told him I was with someone when I filed for divorce. Not with them in a relationship but slept with someone. Well he has since been a tyrant of course in our home. Besides that there is a woman's laptop that has been in our home I have asked him to return it he won't. Well he gave me the password one day to clear the history because she was coming to get it. She never came to get it. A week later I logged into it to use it since its faster than mine and when I did his Facebook was open. I went through it. He was talking to a woman casually after I asked him not to talk to this women since he saw her while separated and he told me she had feelings for him. Well he was talking to her. Another woman was here on vacation in the US. He knows her from back home (Morocco) and asked her to come to Dallas where we live.. She said when she will be in Dallas and he said oh I'll be in Florida come sooner. And she declined and he said I really wanted to see you though :( well I confronted him about it since I don't know her or have heard of her.. He said I had no business confronting her and that he can see whoever he wants without talking to me if its just like a sister to him. And today he has changed the password to the laptop so I can't even use it for recreation... Insight?????
