I think what you feel is a protectiveness of your kids, if I read that correctly. It seems natural to me to be that way. I know I was for a very long time. Still am at times. Why? Because the kids, no matter what else happens, do not deserve what they got. As a father, we protect our kids and this, to me, feels like a time to protect them. Gets my parental instincts going.
I've faced that many times with my ex. MLC or not, there is no excuse for treating a child in the way they do.
But like you I am very grateful for the opportunity to be tested and to be there for my kids in a meaningful way.
Stay focused on being the kids' father. The rest will work itself out...
