I understand the struggle.......as I know how I feel after being in a bad marriage for 33 years.....HOWEVER.....there was a LOT of anger that built up in our marriage over the years & even though I don't continue to feel the anger after I have left.....I know that I would NEVER go back to have a marriage with him.....but then again like I told him when I left....if he ever changed it would be totally obvious even from 2100 miles away because communication was a problem & if he wasn't willing to change & communicate with me over the distance....he wasn't going to change in a marriage where we would be living together......

YOU are showing your change which I totally admire that you are doing & you had a good marriage at one time.....I never did....it started off WRONG & bad.....so I think that it's totally possible for you both to reconcile & for her to KNOW that your change isn't just there to get her back then you will drop the change.....I'm sure that's what she's worried about....so take the time....hold on & make your changes permanent.

I actually have a friend who's wife left him...he is a retired Navy pilot. There were issues & she left before I moved here....& it's awesome because they are reconciling over the miles.....funny because I was from Calif & moved to KY....she was in KY & left for Calif.....he's just a good friend from church that is just a friend so it's nice to see that his marriage that had been separated for over 5 years is now getting back together....lots of changes on both parts from what I understand.
If your wife sees a very sincere change in you......& you both give it a peaceful time to get to know the new you like in the beginning......there is definitely a chance.
