sex addiction is BS, in my opinion. And actually alot of professionals say similar.
And its just an excuse, like the 'you are so sexy/ I cant help it' lines.
Please understand that although rape and sexual abuse have a climatic release to them, they are not primarily about attraction, love or sex - they are about power and dominance. They are nothing to do with the person who is raped, its all a self inward self love and excitement of how powerful they are, a type of narcissus complex, which aligns very strongly with the previous references I made about how he would be feeling good about the one upmanship over your father.
Im glad you are beginning to see that he is absolutely a bastard. I think there is a little crack happening in the mirror he is holding up to you that is supposed to reflect a perfect 'normal' marriage.
And I agree that last night was a deliberate mind fuck - exactly as others say, he had already violated you, very physically by using his strength to force you into a position that you could not have escaped from should he have chosen to continue. He had very clearly shown a 'fuck you' to the boundaries that you and your silly girl therapist had tried to exert over him, and then stopped and threw in a guilt trip as a little sweetie to try to force the focus back to poor him, with his sex addiction and everything, when you were already beginning to reel from what was going on.
I mean, he's good isnt he. He has learnt the book well, the Tate Bro dudes would be proud of him at how he has got away with it for so long and you are only beginning to put up any resistance now.
This is not to say that this is your fault. There is a reason men like this look for young girls who dont have any real life experience, and set them selves up as protectors and experts on life. He is a master manipulator, but thats not to say he is anything special. His type of abuse is sadly very common. And a great many of us here can totally relate to the position you are in where you dont know if up is down or left is right. This is normal because you are living in a complete Alice in Wonderland world, where things you thought were normal are completely upside down, and the perosn who you should be able to trust, is sadly extremely untrustworthy.
The good thing is that you are beginning to question, you do know deep down. You are coming out of the fog. And you will regain your own mind and be able to trust your own judgements. You just need to get away from him.
