Your DDay is still so recent that your WH is really still reeling from one extreme to the other.
My DDay was 8 months ago, and I still feel this way. I can tell you that in my situation, my WH came out of the fog immediately and was completely sure that he wanted our M at a time when I had no F-ing idea if I ever wanted to even look at him again.
During his LTEA, he withdrew from me emotionally and physically. He detached completely for several years and was angry and verbally abusive during that time. After DDay, he wanted to reestablish the emotional and physical bonds way too quickly for me. He expresses intimacy in physical ways: hugging, kissing, touching, and, yes, sex. To have him suddenly making these physical gestures when he had withheld them for such a long time made me feel many conflicting emotions. I felt insulted and taken for granted (so you think you can just withhold any intimacy for years, have an A, and then suddenly, when you want it, I'm just supposed to go along and be happy about it?). I also felt that there was no F-ing way that ANY of that was going to be on his terms at that point. I made it clear to him that I would decide if and when that was okay with me or not.
I don't know what your relationship was like during your A, but your H may be feeling some of that. Like: Oh sure, NOW you want to be with me. He's also processing the fact that he may feel that you chose someone else over him and that he's not sure if he wants to let you back in or not. There are just so many hugely conflicting feelings for him to process.
I can tell you that my WH and I are in R and he is trying desperately hard ALL the time, but I still don't know for sure that it will be enough after the A. Because, unfortunately, the A happened, and it colors everything from now on for the BS.
It's still early for you, I hope that you can just be patient and let your BS sort things out for awhile. You might ask him what he needs from you and how he would most prefer that you express your feelings of love and remorse to him. Maybe all the physical stuff isn't how he most prefers to receive love from you right now. Communicating about it without being defensive or hurt or personally rejected would probably be the best course. Make it about him and how you can most help him.
It might be good to ask him if he prefers that you not approach him in that way right now or if he wants you to keep trying even though he can't reciprocate.
Above all, make it clear to him that you will do WHATEVER he needs and that you're willing to wait and help him in any way you can. He might not know exactly what he needs or what will help, and he might want you to keep up with the physical gestures even though he doesn't want to respond because he's so angry. But he's still there, and communication is really the only road.
Good luck to you on this difficult path. I can tell that you really want to help make this right. I'm pulling for you and your H.
