DG, After reading your latest posting, I have a better understanding of why the ccs where going on. Yes, your h has played the victim card far too many times and hopefully, your sil will see the light. At least now, she cannot say that she wasn't aware of the situation.
Now, he'll either step up to the plate or he won't. I do think you are a very wise lady in being prepared for whatever may come down the pike for you and your family.
I do hope that you can enjoy your Mother's Day w/your children today.
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.
