Although I can't possibly imagine taking her back at this point (not that she'd even try), I also hate my kids have to bounce back and forth and don't have the family unit they deserve and also if I'm being honest feel embarrassed at times I'm divorced.
So what if she said "BL I am so sorry for what I have done, it was a big mistake and I will spend the rest of my life trying to make it up to you and the kids"?
