sure it's possible, how probable, I'll leave that to the odds makers.
you already know that the actions of late pushed her away, so, make yourself stop. when you see her, act as happy as pie, and leave the judgemental stuff behind. put a shock collar on if you have to when you get the urge to slip in a zinger. you need to get used to the reality that she is single now.
you need to not focus on her, focus on you and your kids, keep the X out of the equation.
there was a poster a day or so ago who got divorced a couple of years ago, no contact with his x, he did move on, he was hurting very badly, then, the reason for his recent post was, his X wanted to come back. so yes, it does happen, but you need to make yourself attractive to her again, being confident, strong, and if you really want her back, you need to leave the past behind.
she'll have no interest in getting judged.
am I making sense?
I wasn't very good at forgiving, so I can't help you there, but a lot of good folks on here can
do a lot of reading on the boards, a lot of good stuff. but above all, work on you, not to get a reaction fromher, but an honest inventory or yourself and do what you can do change the bad and improve the good.
