Emotional Affair

My husband was looking at porn on the computer before we moved. I caught him he said he would not do it again. He lived in our travel trailer until our house sold in Idaho. While there he started going to porn again and joined dating sites. He also went on Craiglist to the personals. He first told me that he joined the one dating site 15 years ago. I then found another one. I had him open the email account he was using for all this crap. i figured out his pass word and saw all these emails he sent and received.  I then found more dating sites and porn sites. I dont like the porn site issue. However, I am more upset about the dating sites and the craiglist personals.
He lied to me about when he opened the dating sites. He opened them 12 months ago. He told me he did this because of boredom. He also said because lack of sex and intimacy and communication. I asked him why he didnt talk to me. He said because he didnt want confrontation, I said we always sit down and talk. Our problems are not screaming matches or physical. So that made no sense to me. He was writing thins that were sexual in nature to these women and would tell them when he would be were on business and what hotel. He says he never met anyone and that he stopped doing these things in August. He said he also did it because he got a high off.
So I have been changing things and doing things to make it better. Then yesterday i got up to find an email from a women on craigslits from November. I got really angry and upset again. So he lied again,. He said he quit in August. So it has been one thing after another.
My emotions are all over the place and I am not sure what to do. I did kick him out of the bedroom and I dont give a damn where he sleeps in the house.  I dont know how to trust him either. How do you get your marriage back?
