Waitedtoolong,
I strongly believe once all the main facts, and each one of them, make sense you will start to heal.
You may know the big pic but you need to accept that you will never know the details (feelings, badmouthed, lusting, etc). She would be very ashamed to come clean about it, even if she remembers it. This is very important to move on with or without her.
Infidelity is a lose lose situation, as you pointed out before if she would come clean on DDAy maybe you would have divorced her right away, now that you know the truth and you can heal is too late…
While you are away, in my experience you need to accept that with the fact that:
· Sex with OM was the best she ever had, not because of OM but the rush of the forbidden and the new. She may be feeling guilt every time she remembers but the fact is that sex was so good that she came back for more each time OM wanted where ever he wanted. IMO was just for the sex as there was no emotional attachment (this is just my opinion and I may be wrong and she did it for the attention I just doubt it).
· She cheated because she wanted, there were no external magic forces that made her have an affair. She knew from minute one what she was doing she just took you for granted.
· She is not a bad person; I bet you already know that.
· She is in pain, not just because of your pain, but the plain fact that she cheated: she has been living afraid of losing her world, and grieving for the plans that now will never come, for 5 years. As you stayed in the same house she may trigger every now and then. I cannot tell if she deserves it or not, nor compare your pain with hers, but IMO you should try to release her from her personal hell.
· She didn’t make a mistake, she made a bad decision and carry on with it until get caught. Infidelity is not a mistake; mistakes are not planned and repeated. It doesn’t mean she has changed for the person you married, she is the same person but now you know that she is capable of hurt you.
· I specifically struggled with the impression that WXGF may be thinking, and lusting, about OM while with me. As sex is sex and love is love right? You need to understand that there is nothing you can do about it. I still remember previous, very sexual, relations that had nothing to do with infidelity as I believe everybody else. This is part of each person’s story, accept it and move on. This is just my impression as part of my story is that she leaved while having sex with me to have a beer with one of OM. A beer with him was way more exciting than having sex with me.
· Even if you leave her for good, you will never be the same. You need to work on it really hard. That’s why I am here after 20 years, married to another woman.
· You need to decide to be well and to be happy; it is a state of mind. You need to try every day, it won’t come just because you are separated from your wife.
