I have, unfortunately. But my H's multiple affairs were all disclosed at the same time. I don't think I could go through it again, although some people have.
I'm guessing the first time around, your husband's heart didn't change. He just "said all the right things". Personally, I'd probably go straight to plan D, but if I did want to keep the marriage, I'd have to DETACH from him for a long while until I knew for dayum sure there was a real change in his thinking and his heart.
We've been working on recovery for 3 years now and my husband has SLOWLY been getting a clue. His mindset was a rollercoaster of "saying the right things" and waywardness in the next breath. I am only just now thinking his heart might be shifting in the right place.
But this comes after months of marriage counseling with a excellent christian therapist who is also educated in getting to the root issues, and believes alot of the same things Harley does.
He did see an IC for about a year and a half, but that therapist did more harm than good in my opinion. She was all about his "individual" happiness, and not the marriage. I believe she made him even more selfish and self centered, if that is possible.
Also, I believe the biggest change came over the last two months since he's been going to C.O.R.E. group mens meetings and just recently, a weekend outing. They bared their souls to each other and he came back from that weekend trip "different". I'm still skeptical, but I'm watching and waiting. His mindset seems to have shifted somewhat. I feel safer now.
I used detachment alot during this time. It was that or divorce, and although I was extremely close many times, I saw a glimmer of hope the whole time. That hope is getting bigger now. But, I'm still cautious and he knows it.
Harley says it's almost impossible to get over the resentment of a second affair, so give yourself a break. You don't have to make any drastic moves or decide right away what you're going to do. Give yourself time to think. Kick him out, or move out, if you need to. I'm thinking I would. A second affair is different. You don't need to plan A now. You did that already. Now it's time for plan B, or D.
Just know this.....you do not need HIM. Sure, we all want intimacy, but not from someone who abuses you. He doesn't deserve you right now.
Now is the time to take care of you. Focus on what YOU need, and only you, to get you through this right now.
