I am so sorry to hear the news. What a hard loss for your whole family.
Your story is sad, NLW, and one that is probably quite common when families break up. It does seem that your xh wants to be with you and the kids now. It might be fleeting or lasting. You can't know. If you can, put the past aside and try to see him for who he is today. Let you heart guide you, not your head. It's scary. You could get hurt again. Without egos in the way so much is possible.
Again, I'm so sorry for your loss. Take good care.
