My memory isn't quite as good as it use to be...but there aren't too many posters that I forget. LOL!
It's going to be okay. Just give him all of the space he needs and when he does come to talk to you...just listen. You might be surprised at some of what he says. Sift through the mumbo jumbo and you'll begin to see that his journey was not a happy one and the only thing that kept him from going totally crazy were the memories of his life w/you and the girls. Keep in mind, he didn't ask for the MLC to happen, it just did and like most of them, pride stood in his way when it came to seeking help.
Again, both you have clean slates and I will be sitting right here reading how the chapters of your lives unfold. Who knows what the future holds for any of us. However, I am hoping that you and your xh can find a way to co-parent and be there for the girls in the days, months and years ahead.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
