For me, my real detaching started when I told my H that he needed to completely have NC with OW or we needed to separate. This was my boundary. He wanted to move forward with repairing our R with no transparancy and being FB friends with OW. For me, a strong stance is the only way I can do this. It's not the case for everyone. It's been a 2 steps forward, 1 step back process.
This weekend I found out that he has renewed contact with her. The premise of our S was that he wouldn't see OP. This is really lead me to big time detachment and really pulling back. That's the hardest thing to really do. Pull back. I know I thought he would "forget" me or it would move him closer to OW. Now, I just don't care if it does. I'm doing this for me. BUT, today I'm sitting on my hands to not text him. Yea, it's not as emotionally wrentching as, say, a few weeks ago, or 3 months ago on BD. It's a process. My swings aren't as painful. You just feel it, don't act on it, and you feel better faster than the last time.
