Oh...I didn't know you had met someone you are interested in....
Make sure that you are ready to do this and the fact that you have someone to fall back on is not in play. Can you really be single for the next ten years and be happy? Maybe try through the divorce process first, on a smaller scale!! Lol.
I am truly glad you have found some peace, but I also believe a bit of transference is happening as well. Just be aware.
That being said, only you know if you are moving on. Forgiveness does play a huge role in this process and you if you truly want peace, you will have to forgive wife for not being there for you when you needed someone.
