Too lazy to look through all 4 pages so I will ask my question anyway.
I have always wondered why a man would get off by watching another man screw his wife. what is in it for you? Why don't you get jealous? Do you ever join in (no crossing swords of course). I am not being snide, I really want to know!!!!!
As to your situation, it sounds like you have ripped every little bit of self esteem and trust she had in you. After all this time, you are waking up, but she is still holding tons of regret and anger against you. Any woman would. Any man would.
Another question: it seemed you loved running around and doing your own thing knowing she would always be there. Are you just panicking because now the future may not be so clear? If she forgives you and you guys live on as a married couple, will you get bored? Are you sure the desire to cheat won't raise its ugly head again?
You need to work on yourself before you can work with her. You need to find out WHY you did what you did. Self reflection is so important. Maybe once you know why you did what you did, it will help to clear your mind. If she sees that you are working on yourself (counseling) to get better, she may soften. Marriage counseling is not good right now because she is still too filled with rage and betrayal. Actions speak louder than words. Become a better man and I am sure she will notice.
I am glad you had to guts to spill your story here. We certainly don't hate you, but it sounds like you hate yourself. But someday you are going to have to forgive yourself and work on improvement. If she decides she doesn't want to be married to you anymore, that is going to hurt like hell, but with the counseling, you can sort of get ready for it emotionally so you will know how to handle it.
Hang in there my friend.
