Trusting, I'm so happy to read that you and your xsil bumped into each other. It explains a lot of why you haven't heard from her. You have to wonder as to what else he's told people...you? crazy? I don't think so.
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.
