I feel broken. (Updated)

I should start by saying that I am pregnant so hormones are undoubtedly playing a role in this, but I just cannot stop crying. I have been more interested in sex than normal the past month or so and definitely communicated that to him. I try to send flirty texts and basically told him I am down whenever and for whatever he wants. We were laying in bed tonight (it was late) and he said he was going to go get a workout in the garage. Fine. I claid there for a while and was not falling asleep so I went downstairs to check a load of laundry and hear him out there jerking off. I stood by the door for a minute, unsure of whether I should open the door or say anything. On one hand, I would never try to tell him what he is allowed or not allowed to do, especially with his own body. On the other, I immediately questioned why he did not attempt anything with me. Literally, the last thing he said as he walked out of the bedroom was that he loved me and I was sexy...but in kind of an offhand way...not in any way coming on to me. I am so confused about how I feel right now. Mostly hurt and unwanted. I do not feel like I have a right to be angry even though I am a little bit. I just feel like how disgusting must I be that he would rather go out in a cold and dirty garage and jerk off than take advantage of his willing wife in his bed? Also, the last couple of times we did have sex, he never finished no matter what I tried. Even with my hand and/or mouth, which has nothing to do with baby. He noticed I was upset when he came upstairs and he said I was just overreacting and that he does find me attractive, but how can I believe him? Worse, if he does try to initiate anything now, I am going to feel like it is out of pity. How do I stop this negative spiral?😥

To be clear, I have no idea if he was watching porn or not and it does not matter to me if he was. I do not consider this any kind of cheating and am not worried that he would cheat on me. I know he loves me...I just feel like the lust/passion is MIA.

UPDATE: He did not understand why I was so upset last night. I had a really rough time sleeping and ended up spending the night on the couch. After calming down and having a bit of time to think and sort things in my head, I went upstairs this morning to get a notebook so I could try to put into words why I was so upset. He was awake and asked to talk. I explained as best I could that this was a buildup of things over the years that I bottled up and thought I had let go, but obviously had not. Last night was just the metaphorical straw that broke the camel's back. If he had told me that he was uncomfortable because of the pregnancy, I could have dealt with that because it is not personal. The thing that made me feel so awful was that I felt completely undesirable. My husband is the only partner I have ever had and I internalized it all and assumed there must be something wrong with ME. He apologized for upsetting me and assured me that there is nothing wrong with me and he is just hard to get off and thought I would be asleep. I am still struggling a bit, but do feel somewhat better. Thanks for letting me vent, ladies. I truly appreciate the support. ❤
