Turmoil with husband which is making me sometimes want out

Currently pregnant with baby number 4 and have a husband that just doesn't get it. It's literally 1am. My husband just came to bed and earlier he seemed to be short with me for unknown reasons but I assume because I went on a work outing that he knew about. Anyway I was annoyed with him being short with me so I took a shower and went to bed. Hours later he comes in. I try to make the tension go away and lay my leg on him in order to try to get his attention... This man gets up out of bed and literally try to say he heard something 😒, knowing dog on well he happened. Spoiled the mood completely. I asked him why he's running from me, he gets back in the bed and half touches my hand. I'm over it.. Forget sex... but this happens a lot that he spoils moments and makes me feel like I'm not really wanted. Intimacy sucks and it is making me want to not deal with this any longer. Like do you want me to cheat because you're pushing me and totally oblivious or careless. Like he feels I'll just be here taking this. We've been dealing for 17 years and I'm crying in anger right now due to this. I know it's not Christian like but I'm struggling even when I've had conversations about this in the past. Idk if I'm coming here for advise or just be vent but I'm super over it right now.
