You are being given a very rare gift of actually getting info on what transpired in your h's young life.
I do think that your MIL is starting to see the light and coming to understand a bit of what is going on w/her son. She's doing a lot of soul searching within herself. It's best to listen and nod your head when you hear something that you know is correct. I wouldn't be too willing share much of what is going on w/you at the moment.
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.
