Continued Lies

I am right there with you. About six months ago my husband started acting like he did not ever want to be at home, resentfully toward me and began disappearing for hours at a time. He always said he was out with our mutual friends and his phone died. Two months ago he asked me to move out for a separation period because he was going through something and needed some time away from me. I did as he asked. Next day he asked me to come home. Three days later was Valentines Day. He disappeared at 9am and never answered my calls or messages. His friends saw the messages I sent to them but would also not respond. He did not come home till midnight. No his special dinner was ruined. He did not even say happy valentines day or get me anything. One of his friends hinted that I needed to check who he hangs out with, but she was one of them. He told me he had done nothing wrong was sorry about being and jerk, h is head was back straight and loved me. Two days later I find pictures of a girl in his computer. He said that while it was wrong, he was just talking to her and messaging , he had never touched her or anything inappropriate. Three days later Ihe finally admits to have a year long on going affairs with her, loves her and will not stop seeing her. She is a local prostitute. A few days later he apologized again and said it was over and he was devoted to getting our marriage back. Same night immediately after being intimate with me he starts texting her on the phone. Bold faced lied to me about what he was doing but there was a mirror behind him so I saw it all. How do I ever believe him when he can hurt me over and over while lying about it to my face?
