How to get over betrayal?

Almost a year ago, my husband left me for about 3 months. He wanted a divorce he said he didn't love me anymore, it was horrible. There was another women involved but he still claims to this day that nothing happened between them, that everything that looks like they slept together is not really that at all, he claims they were just friends. I don't know how you can talk to some other women on the phone for literally 5 hours and still consider that just a friend or have her spend the night with him in his room .... Anyways he took me back after me chasing him over 2,000 miles away and a lot of begging "it was like I had to win him back, even tho he cheated and left me" he was a jerk to me at first but, here we are now almost a year after he left me, and it feels like all of this drama happened yesterday. I am worried that if and when he gets deployed he will fall for another women, and I will just be hanging around waiting for him. The thing is, he says with me is not exciting, he likes to have like once a week, I always make the move on him otherwise he wouldn't try, if I get upset with him or something he wont bother to ask whats wrong, I think he prefers the silence. I feel like a consultation prize like he's settling for me and takes me for granted. I don't know what to do, I do love him obviously but I don't like being treated like a door mat. what should I do? I am in desperate need of some advice.
