Just caught up with your sitch. You are doing well except for the cake eating you let your W have.
It's hard to not dwell on those small things they do to draw us in.
I too have kids that want nothing to do with my W. 13 and 15 yr old. W did some pretty selfish things that were abusive verbally and emotionally to them so she could find herself.
I like that you have stepped out of their relationship and left it to W to fix it. Your son seems to grasp this whole thing well. As long as he isn't holding every emotion in and he can talk to someone.
I'm a few months more into this circus but I still have my dreams and thoughts drifting to W. I'm lucky in a way mine is a vanisher. She is with OM so I won't entertain being her friend or forgive her at this time. Later on who knows. It's the damage to the kids that gets me wound up and will be hard to forgive.
Be strong for you son. He is watching you and will learn to be a better man.
All the best to you Irish
