I read your sitch. To be honest, your H is not respecting you by having sex with you after D. He is definitely having his cake and eating it.
I agree with other posters, you want to go dark. Look at the situation now. You are D, which means you are not held accountable for what you are doing, you do not need to tell him your life, except for the baby. H is D'ed. He does not need to tell you what he is doing. But currently he is doing whatever he wants, and you are told to sit at home, and have sex with him at his convenience.
He can make a choice. If he is committed enough to come back, he needs to stop seeing OW, and other woman. If he does not want to, that's also his choice (well, he is single now, afterall)
SO2, it is difficult for you in this situation, being pregnant. ExH is the father so there is every reason to go back to him. However, at this stage, I agree with others, you are better off going dark and do things because you are single. You actually can date like your H. (not saying you should). However, i think you may try living life as if you are a single mom, without ex. He is feeling that he can still have you in his life while partying around. He is not respecting you. For the moment, may be it's better to be independent from him so you are not affected by his actions.
Take care, it will be tough with the pregnancy.
