Yeah it is hard. Trust me when I say that your H will be ready to accept his role in your M some day, but initially he is going to feel like a doormat for working on a M. He has to be in a much more secure place before he can handle any of that. You have about a year head start, so it makes sense you are ready to move forward. He isn't and nothing you do or say will help him catch up. Use your stronger position in this to help him find his mojo again.
His self esteem is way to fragile to do any introspection right now. That has to be rebuilt and he has to do that himself. You can help jump start it. Compliments, love notes, a a partcular type of attention that most men adore, praising him for the things he has always done well (yard work, taxes, good paying job/supporting the family, is the best trivia player in the world, etc.)
He asked from the three month timeline and chances are it is going to hurt for him to read it. Any timeline in this space is going to hurt.
BUT he asked for it, right ? He wants to understand what lead up to the affair.
Maybe you could preface it before he reads it by telling him (in a letter if he has trouble listening) everything you have said here. Qualifying that it does not excuse what you did and you don't think about it that way. He should either. For some reason words written down are easier to believe.
Explain that your understand it is important for him to gain some insight into your thought process and you are using it as tool for both of you. Expressing some remorse would not hurt either.
Use I was feeling and keep it about you. There are many ways to word the same statement.
I felt lonely (ok, but not very deep)
I felt lonely because you never talked to me (putting blame on him)
I felt so alone most days. It was very hard on me. One of my happiest memories was the time (in said 3 month period) we took a walk in the park and talked about . . .(fill in the blank). I felt so respected, loved and happy.
You express the feeling, point out there were times he got it right (confidence builder), but keep most of it positive. After all he needs to see that there were times you were happy pre-A.
If you haven't I would read the 5 love languages by Chapman. There is an online test too. I can't tell you how much easier this gets once you speak each others love language. Even if you ask him to just take the quiz and start trying to approach him in that way. Somebody has to take the first step and unfortunately he is probably looking for you to do that.
www.aftertheaffair.net has a really good E-book on it. I know it is somewhere on the wayward book list. Just reading a booking is good way to show your dedication to the M. Maybe he just needs some inspiration or a way to start or doesn't know where to start.
If your husband is a guy-guy (like me) remind him that working ourselves to be the best that we can be is the manliest thing on the planet. Being in touch with who you are and who you want to be makes him a stud. Worse case it makes him happy in a way no person outside of himself can. No matter what comes into his life all the tools he needs are always with him. No one can ever take that away, it is something he can always count on . . .himself.
Look, I have lived the other side of this. The M issues will have to be addressed, but it isn't going to work if you ignore the trauma your husband is feeling. He might be angry, but underneath anger lies a whole lot of pain. Anger is a secondary emotion, there is always something underneath it.
He feels that much anger and underneath it the pain because he loves you so much. If he did not have any reaction I would be worried.
The emotional versus physical connection thing is very common amongst M couples. Both need their version first before they can do the other.
Just like you didn't feel comfortable being intimate without an emotional connection, he probably didn't feel all that close to you without a physical one (there are many ways to establish this BTW, not only the one you think I mean). Biologist refer to it as "natures birth control." Funny, but cruel joke of nature.
You took a little license ascribing feelings to him that he may not have had. Be fair to him, doesn't he deserve a little credit. He is still with you trying to work this out, right ? If you do anything today, just thank him for still being there.
