Naked Chick Pics?!

So my bf and I have been together for almost 3 years and the other night I caught him looking at naked pictures of chicks online while I was sitting in the same room as him. I looked over at him and in the reflection of his glasses was a naked chick.. well obviously I was staring hard to make sure that's what it was before I lost my shit. It was.

I asked him if they were hot. He acted like he had no idea what I was talking about and closed his phone. I said the women you're looking at, are they hot? Then I asked him to open his phone and he told me to go fuck myself.

I was shocked, because he never has yelled at me before.

Now I should say I'm 4 months pregnant and incrediblyyy emotional and just feeling like a hormonal mess. We hardly ever have sex and he blames it on my morning sickness. (haven't thrown up in over two weeks) I've never told the man no for sex or anything sexual, even when I have felt like death, and for him to be so blatantly disrespectful was heart breaking. I tell him all the time I want him and how I can't wait to fuck him or suck his dick when he gets home, and then nothing comes of it. Which makes me feel even more self conscious than I already do.

He said he didn't do anything wrong and that all he wanted was to look at some titties.. UMM HELLO you have two big ass DDD titties sitting on the other couch 5 feet from you. But apparently mine aren't good enough for him.

He's been jerking off alot lately too and even signed up for some amateur couple porn site to download pictures to jerk it to. Now also, I have to say that I have a huge issue with dudes masterbating. My ex husband jerked off in front of me once and it bothered me to my core. I was raped at 6 by my babysitters husband. He used to jerk off in front of me, and on me all the time and make me jerk him off. I can't even watch a random person jerk off on porn because it disgusts me so bad. My current bf knows this and how it has fucked me up over the years, and he still has no disregard of doing it while I'm home.

He watches porn in the living room while I'm asleep and I wake up to chicks moaning and it bothers me.. and I get the "I like to jerk off and there's no where else to do it, so I don't know what you want me to do".

Ever since I told him I've been pregnant our sex life has declined tremendously. We used to have sex 2-3 times almost every single day and now it's barely once a week. He sleeps on the couch and never comes to bed.

Am I overreacting because of hormones and should just apologise for being a psycho or am I in the right to be upset that he was being a douche for looking at other chicks while I was in the same room?
