Sexless marriage. What is wrong with him?😢💔

I’m 26 and my husband is 28. He used to ask for sex all the time and would always try to be very touchy. Now I get nothing. He barely looks my way, he doesn’t ask for sex or initiate it. I could be in the bed half naked and he doesn’t even try to touch me. We haven’t had sex in days and the last time we did it because I asked. I have gone to him multiple times about this and expressed how I felt about it and all he tells me is that he is just not in the mood. I get that every once in a while you may not be in the mood to have sex because sometimes I’m not either. But days without sex with your wife? And then I went in his search history on his phone and I noticed that he looked up porn and when I confronted him about it, he said that he didn’t do anything to it.. and that he just watched it. He tells me that he loves me, and that he is still attracted to me, but yet he doesn’t act like it and then he’s watching porn on his phone?? I’m honestly so embarrassed to even mentioned this, but I did find out that he cheated on me a few months ago with a coworker at his job twice. And ever since then we have been fighting and things just haven’t been the same. I’m 8 months pregnant so that adds on top of everything. I just feel gross, not wanted or loved. What do y’all think?
