Husband choosing porn over me?

Before I go into detail, I would like to explain our sex life. My husband and I were very kinky and had sex 1-2 a day, everyday! We would always buy toys, use cuffs, try all sort of positions, etc. I was really happy to meet someone with the same drive as me and I am sure he was happy as well to have such an experimental sex life since he never got these opportunities before. I am the kind of person who has always aimed to please him.. I never say no and I hate missing days of sex.

Anyway, he was the same and would also aim to please me or at least make love to me because we were still in that honeymoon phase. I got pregnant right after our wedding and we have been married for 7 months..

but since we got married he didn’t want to use all the expensive toys and accessories we have and he doesn’t even any sex that much now. I tried letting it go since I know pregnancy can make men feel weird about sex but I just found out he has been watching porn at work behind my back. I’m frustrated and hurt because During this whole pregnancy I’ve worn lingerie to bed, always ready to make love, even spoil him with blowjobs after work. Most times when I ask to have sex he says he’s tired and we will do it another day.. but then when I ask a few days later he says he just wants to do a quickie or nothing at all. It’s almost as if me being pregnant made him lose interest in our sex life. I joke all the time about how we have to get it out of our system before the doctor makes us wait a month after delivery and he still doesn’t try to make love to me...

I know some of you might say I’m being dramatic but we had a long history of having sex daily and trying out all sorts of things from our local sex store. I just don’t understand if he has a pregnant wife willing to still being sexy and available why he is going behind my back to watch porn and then choose to not be intimate with me for long periods of time. I’m about to deliver our baby in less than 9 weeks and I feel like our sex life is going to continue to become a thing of the past and he will keep looking at porn daily at work.

Sorry for long post.. any advice on how to deal with this?
