No, you didn't break him. Life caught up w/him and now he needs to go back to a time where it all began and figure things out and then grow up. He's stuff his childhood issues down so deep in his soul and the events of the last year or so have brought them back to the top to be dealt with.
He's right about one thing, he's not the same person that he was before and both of you will discover just how true his words are.
The best thing you can do is take care of you and your kids. Protect your assets and what your financials. Don't rely on him because he's going to start slipping up. Expectations at zero at all times because he's not the same man you knew and yes, they become experts at lying and hiding things too.
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.
