Be careful, jeaux....people may try to start arguments with you over there about things you say over here, and misrepresent you in the process.
Reading that thread (and unwisely commenting, which I should not have done) has just reinforced my belief that the only way to deal with this sort of betrayal is to try to make the OW irrelevant. Horribly, horribly difficult, of course. But when I read through that thread, I don't see people on healing journeys.
I was once counselling a friend through her husband's affair. She was indescribably hurt and damaged, as you can imagine, and couldn't imagine things ever being right with her husband again. I gently reminded her that she had a choice as to whether or not to stay in the marriage. She looked at me, horrified, and said, "But if I don't stay with him, that fucking slut has won!"
I didn't want to trivialise her pain and I know we're not rational when we're angry and hurt. But she stayed with that bastard for much too long, and caused herself endless unnecessary pain, because she couldn't free herself of the fucking OW and make a decision based on herself and herself alone. If she'd been able to make the OW the inconsequential gnat that she should have been, she'd have seen much sooner that things couldn't be saved (her husband was a total arsehole) and spared herself so much pain and time.
You can't live a life where your happiness is dependent on someone else being miserable, even if they were absolutely vile to you. Take any two people in the world and there will always be times when one of them is happy and the other isn't. If your partner cheats and you decide to try to work through it, you will not heal as long as you're always out to sabotage things every time something nice happens to the person who, well, isn't in your marriage.
