Husband not interested TMI 🚨

So normally my husband and I have sex a lot like multiple times in a week, sometimes twice a day until I got pregnant. I am now 32 wks and I feel like he’s lost interest. I came downstairs and found out he was taking care of the deed himself last night, while I had been asking him to come up stairs to me and have some us time. But he said no he didn’t feel like laying down. I asked him what he was doing and he said nothing and lied about it with his pants halfway pulled up and eventually said okay yes I was masturbating. I know people masturbate and I take care of myself too but the fact that he picked porn over me (yes I know I haven’t been saying yes every single time but most of the time I try to have sex. My sex Drive is like gone since I’ve been pregnant) it just made me feel like shit. A few weeks ago he also told me he was talking to escorts locally to just jack off and he never saw anyone and had sex with anyone. That was really hard for me to take. He said it started since the beginning of our relationship and it’s almost been two years. He said he only did it once while I’ve been pregnant and it was to a transgender person but he felt horrible after and he came clean and told me while we were in the shower. I haven’t always been loyal I did mess up actually sleeping with someone else (don’t judge) but since I’ve been pregnant and awhile before I got pregnant we were inseparable and chose to work through it and we had a really good bond. It’s just after last night I still have doubts in him as well, because of those situations. I feel like our bond has weakened and we barely talk some days and barely have sex if that once a week. What do y’all think?
