Re:what to do - contact WA, the organizations the commenter above has mentioned, ask for your friends' help. You told them for a reason.
You know you have the strength to take action when you keep coming here and asking for advice despite the thread getting frantic at times and things being hard to hear.
Some of the steps these orgs advise you take may continue to seem drastic to you, but your therapist and whoever will advise you need to hear about what he said to you, which is a dealbreaker IMHO. He thinks that "in a loving relationship he could try his luck" and rape you after what you told him.
This is just my opinion:
He can try his luck = Your trauma, his abuse of you is a game to him. Several comments have pointed out your resisting (in the situation as well as for a week) and "surrendering" arouses him, and that's the only thing he cares about. It actually reminds me of how addiction works - the looking forward to getting their fix is part of it just as much as the fix itself.
Even more alarmingly, he wants to set the terms for not just a "relationship", but a "loving relationship". Why now? Because his good behaviour, his plying you with gifts was at least in part an act, calculated to prepare you for the next assault. He hasn't just rejected the fact that abuse has occurred and keeps happening, he believes abuse/rape are part of a loving relationship, which they never are and never can be (unless they are part of an explicitly sexual fantasy shared by two consenting partners who each agree to engage in that fantasy).
He either has no understanding of what it does with you (unlikely, you told him, he witnessed that night terror - if he isn't the cause himself), or he doesn't care. Whichever is the case, as a consequence he's not just trying to justify his abuse, he's trying to manipulate you into conflating love, sex, abuse and rape.
There are not enough gifts or acts of kindness in the world that could justify his doing this to you even once, nevermind repeatedly after you told him what it does to you.
