People don't do anything because of others, it's always self motivated. W didn't ask you to do anything becaue she didn't love you, she was thinking about herself and how she felt about the situation. I know it's difficult not to take it personal but her actions were about her, not you.

As for the family, I wanted to know if it's something you want to rebuild at some point. I understand there would be difficulties and the history is complicated. You personally, what would you like to see happen there and why. Keep the thought independent of how it effects W and the MR for now.

Accept what is, let go of what was, and have faith in what will be
