Your plan is a start. Perhaps the best way to begin is to get him out of your life completely so you quit feeling like there can't be anyone else because he's so important. I used to feel that way about my first wife, that I'd always have feelings for her. I don't think it's possible to know that until you let them go completely. Now I know that I wouldn't always have feelings for her. Maybe it's just me, but my XW never meant more to me than my second wife just because she had mother to my kids status. All that means is I have to see her more often than I otherwise would.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
It is hard to fail, but it is worse never to have tried to succeed. Theodore Roosevelt
