Start tomorrow by giving your son a card. Resist putting down W's actionswhen chatting with your son. Concentrate on rebuilding your R with him and other son.
Accept where you are in your M. Rebuild you and R with kids. I would add caution to not enter into a game of one upmanship each trying to outshine the other. When you are the best you can be, decide what you want to do about M/R.
It is tough. Good luck.
