“as time goes on I resent my partner as I hate myself for "giving in" and because I am trying to reassert my freedom to choose.”
Your freedom to choose whether or not you want to have sex with your husband on any given day or time is a basic human right. Please never forget this.
“Our sex life is non existent and started off in his words brilliantly. He knows about my past and he just wants things to go back to how they were.”
How grim that he wants things to go back to when you were having sex with him out of a trauma reaction, rather than cheering you on to a future when you have sex with him out of freedom of choice.
“I know feel that I have come from a place of having no self respect to having some. I want my wishes and feelings respected."
You have self respect and want your wishes and feelings to be respected. That sounds perfectly normal and healthy (and massive, massive kudos to you for getting to this point!). Most women need to feel that their wishes and feelings are respected before they feel like having sex – it’s not a big ask, in fact it should be the bare minimum for anybody in any relationship.
"He thinks I bring it all back to what I want.”
So what? You are allowed to bring it back to what you want. If one person wants sex tonight and the other doesn't, the ONLY ethical result is that it comes down to what the one who doesn't want it, wants. Sex requires enthusiastic consent from both parties. If one has stopped saying an enthusiastic yes, then the only reasonable way forward is for the sex and pressure to have it to stop, and the enthusiastic partner should turn their efforts towards understanding why the other has lost enthusiasm, and do their best to support them and to provide what they need. In this case your consent was likely based in trauma survival mode, rather than a true enthusiastic consent, and it is perfectly reasonable to say no a LOT more when you start building healthy self esteem and boundaries. If he is a decent and loving partner your desire will return in time, and the sex will be a thousand times better as a result.
Have you seen the tea and consent video?

It’s healthy and normal for you to want your wishes and feelings to be respected in your marriage, particularly when it comes to sex, and even more so with a trauma history. What you want is perfectly reasonable. He sounds like he’s sulking because he wants sex without having to put in any of the basics that go towards a woman feeling safe and loved enough to want to have sex. Another way of putting it is that he appears to want to have sex with you, even when he knows that you’re not feeling in the mood for it. Would he rather you just shut up and put up with it than him have to make the effort to find out what he needs to give to you so that you feel safe and supported enough to feel desire for him? If so, that's pretty grim of him.
“So question is AIBU to not want to just have sex on his terms or I am I making it about myself?”
Nobody should be having sex on one person’s terms. Your terms have changed – you’ve done some healing and have come to the extremely reasonable conclusion that you deserve a choice, respect and dignity before you decide you’d like to have sex with your husband, A decent partner would be absolutely fucking delighted that your self esteem has become so healthy and that you are healing, and getting to a point where when you agree to have sex it is a full bodied “HECK YES I REALLY WANT YOU!!!” … and not compliance in trauma response.
Heck, even the prostitutes he has slept with didn’t have sex all on his terms. They had prices, and (hopefully) behavioural standards that clients had to keep to, agreement on what they would and would not do. (I think him going ahead and having sex with prostitutes is an awful thing by the way, and it doesn’t matter if you suggested or agreed to it, a man who is willing to sleep with a prostitute is one with a massive red flag over his head over how he feels about women.)
Keep going with the EMDR and the therapy, you sound like you are doing absolutely brilliantly!
You are not unreasonable to want to feel respected and to have the freedom to choose whether or not to have sex.
