Yes. Well, I have gone to IC, but that's it. No MC, and WS did no counseling.
My IC was not long. It helped, but I only went a couple of months. DDay was nearly 3 years ago. The A ended over 3 years ago.
We spent last night watching boardwalk empire snuggling under a blanket, giggling like kids. No A talk, no A thoughts, nothing. We are very happy.
I did a lot of work, and he really changed, a lot. He is like that - he sees something he wants to change, and bam - changed! Me? ha!
So he changed, a lot. An extreme amount. He is a different person really. More open, more loving, happy to be here, married. He had built up 'resentment' to it all because he felt life was passing him by. It was a midlife crisis. He changed completely. I did what most BSs do - learned everything abut affairs, WSs, BSs, the works.
So yes, you can do it, but the two people have to really want it, and they have to do the work required for change and learning about themselves. There is no substitute for that.
