Welcome to SI. I see that you noted a few times that this is your fault, and I am sure that you are in a lot of pain, and unsure of how to feel or what to do. However, your accountability and empathy are non-existent at this point. You said that you cheated on your wife for 8 years straight, with multiple people and encounters. Everything in this post is about YOU however, about what she is or isn't doing to make things better for you, whether or not you are in your own bed, being made part of her life, being made the object of her affections... honestly, if you had left the first sentence out of this post I probably would have assumed that you were the BS she was the cheater! (I realize she had an RA of some kind, but it also seems that her RA never would have occurred had you not betrayed and lied to her for 8 years straight first).
I think the first thing you need to come to grips with is who you are in this situation, what you did, and who is owed what. She's not the bad guy here. She doesn't owe you anything. I'm terribly sorry to hear that things in the marriage weren't what you needed them to be before this. It sounds like you both have some issues with alcohol, and with intimacy. When those things occur in a marriage, we have choices. We can talk to our spouses. We can ask for counseling. We can demand better. We can decide to leave. We can decide to stay. We can ask for an open marriage. And doing any one or more of those things would have left you with your dignity intact, and hers as well.
The truth is however, that nothing she did, nothing about the marriage or the drinking or the sex or anything else, "caused" you to cheat. Unless someone put a gun to your head and forced you to cheat, then it was a decision you made, and an action you took. You own it, 100%, because it was your decision to do so, and it was made without her knowledge or consent.
Imagine walking down the street one day when a man jumps out of the shadows, beats you nearly half to death, and then steals your wallet. As you lie there bleeding, blindsided, in pain, confused, robbed and near death... the man starts to tell you how much his hand is hurting from beating you so much, and he's very angry with you about it. He says he took the bus here and asks if you can drive him home, and when you tell him to F off, he says he doesn't understand why you are holding on to so much hatred when he clearly isn't beating you up anymore, so why are you still so mad? You get up to walk to the hospital and he stops you and asks, "Where are you going? You're gonna go mug someone else without me, right? Yeah, seems like something you'd do. Don't expect me to not retailiate."
Your story sounds similar to that. I don't understand why you feel she should take you back, or show you any kind of love or intimacy? Let me ask you this... what's changed about you since the affair? How are you different now than you were during the past 8 years when you lied to and betrayed her? How are you safer? How can she be sure you won't cheat again? What have you done to make up for what you did? What have you done to earn feelings of romance or even forgiveness from her?
I don't ask/say these things to be mean to you. I'm a WS too, everyone in this forum is, so we've all been in your shoes at some point. This is not a judgment of you, it is an observation. I want you to start to really see yourself, not through all the lies and excuses and justifications that you told yourself in order to feel better about having an affair, but to see the real you, the guy who hurt his wife and is now mad at her for not forgiving him on terms that are convenient to him.
If I can offer any advice at all, I'd suggest seeing an IC instead of (or in addition to) MC at this point. You are just not emotionally and mentally at a healthy point right now. Until you can start to see yourself, you won't be able to see her. And until you change, and give her reasons to even think about forgiving you for what you did, you need to understand it, and come to a place of remorse and contrition. Stop expecting her to forgive you without a reason to do so. That only happens on TV and in the movies. In real life, people who cheat, suffer consequences for their actions. It's not a punishment, it is how life works.
