A, I'm very sorry to hear about your daughter's situation. I do hope things work out for her.
You know your h and your situation far better than we do. If you feel that you do not want to respond, then don't. You'll know when the time is right.
Please take care of yourself.
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.
