I'm sorry you took a hard tumble. You may need to rest the ankle(s) for a while and not try to go walking this weekend. The bruising takes a while and you may have injured yourself more so and the aches and pains haven't set in. Rest today and see how you feel tomorrow.
As for your h, I think, and I could be very wrong, was trying to manipulate you. It's his one last ditch effort to have you rethink divorce. If he knows that he's close to having a "break", he knows what he needs to do. He still wants you to be there as his lifeline or rather his "mother". Someone that he can talk to about this issue. Your advice was spot on and that's why he's quiet for now.
Take care of yourself and keep your focus on your life, family and schooling.
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.
