him lookin at porn?

I am engaged to a man who I really love. He was the one who wanted to date me so bad and I kept turning him down because I was wanting to go on to medical school and I thought a relationship would hurt those chances. Finally I decided if he is the one than I am really hurting my chances so I said yes. I really love him and we got engaged last September. I didn't use to have a hard time trusting him until I found a stripper game on his cell phone, and I was pissed. He lied to me about it and said he had no idea where it came from, and I am smarter than that so he finally confessed. I forgave him because it wasn't the cartoon strippers I was mad about, it was him lying. I am not okay with porn in any form, as I find it degrading, and no one can compete with that. After all how would most guys feel if you were fantasizing about some other guy during sex? Before we started dating he admitted he used to have a problem with porn and it has since stopped. A few months after the phone thing I found out he registered at a raunchy dating website which he again denied but there was a username at the top only he would have picked, so I was again, smarter than he thought. He apologized for that and we almost broke up. I told him he can't lie anymore and he said he wouldn't. I felt sick and wanted to throw up on him so I didn't talk to him for a few days. A few days ago I knew he looked at porn and crap again and I asked him and he told me the truth. That he looked online and rented some movies from the store. I just about died. That after all that he would do that...he knows how I feel. It makes me feel terrible since I was made fun of so much throughout my life. I know he loves me but I can't trust him very well and he says he won't do it again but I can't make myself forget. Also when we're in bed he won't look at me. He always makes me face away and calls me mean names. I don't know what to do. Does anyone have an opinion?
