I'm reluctant to talk about this because I may have to dodge some 2x4's.
No bashing please
It's this theme that I think you need to look at.
First, why would you dodge the advice? The 2 by 4s are meant to help you see a different way of thinking. Without the 2 by 4's I would never have gotten through this thing.
Second, that you see it as bashing rather than people being helpful. Sure, I think we all get unhelpful stuff, projections of other's situations. But, for the most part, just try it on. If it doesn't fit, discard it.
I do not understand your aversion to talking about this with your wife. I think she is trying to work though this. I personally think that what she said DOESN'T help you feel better, that's not unusual. But, what she is saying is that she was selfish. This is a correct and needed admission to make.
If you really want to save your marriage don't be afraid to talk this thing to death. Honestly, the more you hold her back from that the more time it's going to take her to heal. She needs to commiserate with you. And, sometimes she needs to be corrected on her thinking.
The other time you brought up the blow jobs, you did it in a way to shut her down. This time you didn't bring it up. When there is true progress, you will be able to express your pain around that not as a deflection of your own behavior but when it's appropriate. I personally think it might have been appropriate to say what you were FEELING. "The pain that some of the sexual details of what you did is enormous to me. This analogy you are making feels like a minimization of what actually happened."
Either you are past it or you aren't. Your posts all read like "ignore it and it will go away".
And, then when we try and reflect back for you ways you could do better you think it's a 2 by 4 or bashing.
It took me a long time to learn how to talk about my affair in both a very candid and honest way but with compassion towards my husband. But, once I did, I have never been afraid to bring it up. I have found the more I brought it up the less he felt a need to do that.
Now that the shoe is on the other foot, I need for him to bring it up so I know he is carrying the burden with me. That I am not alone in that task. The more you all talk about it and gain clarity the more empathy with each other you will build. The thing that you want to shut down is actually the keys to the other side.
I also think if you look up a vulnerability hangover you will find what she is doing to be very normal. I have noticed most BS do this. The best way I can explain it to you is that there is still a lot of deep hurt to be let out. When we have a good night or a good couple of days, I don't want him to get the impression I am over it. It's very uncomfortable because then it becomes rug sweeping. Rug sweeping is what I think you always sound like you want. But, what your wife is doing is more productive for the longer term.
If you truly want to save your marriage, bring it up, talk it to death. If she sees you are doing that she won't feel the need to do it as much and there will become more balance. And the more you talk with each other the better opportunity for empathy and creating a new marriage.
This wasn't bashing or a 2 by 4. Really just this is the path. I think it would help too if you continue to work on your wiring. You keep wanting to seem like you are good to go - you say things like you see the OM and were friendly with him. But, underneath it all there is still a lot of anger and resentment, otherwise you wouldn't keep feeling the urge to throw out the sexual stuff. Instead of throwing it out to shut her down, throw it out when it's appropriate, and relevant.
There is a poster here, that I wish he would have written what he did earlier because it opened my eyes and changed the whole way I approached R. I think the post got put in the quote area, I will see if I can track it down and link to it. It is a far better explanation than what I am giving you.
If you want to save your marriage, this is the way - open it all up, look at it all very closely, leave noone behind, talk, talk, talk, talk talk. You will never be sorry when you see where that takes you.
