Bummed

Me and my husband have been having issues in our relationship lately. He cheated on me a few months back and I took upon myself to forgive him and work things bc he said he made a mistake and blah blah blah. However I just don't feel like he's doing what he needs to do to repair our marriage or even win my heart back. But then I don't want to make him feel like crap for trying. Anytime we have discussions like this he always throws the "nothing I do is ever good enough for you" card. I sometimes feel like he sees it as okay he has me back so now everything's okay and he does t have to make up or try to make things better for us. I can't talk to him about this bc he always says I'm living in the past and I need to move forward. That is true. However I feel like how can I let go of the past and move forward when he's not doing his part as a husband who wants his marriage to work. Our sex life sucks. Everything just sucks. I sometimes feel like it's more of a job then a marriage or relationship.
