Yes, you are becoming stronger every day. Who knows what is going thru his head...maybe he wanted you to find out so that you would take action first. Your h is a piece of work.
Please do not let on to him that you are aware of what transpired. That's something you keep in your back pocket until you need something, i.e., like a bargaining chip.
Take care of yourself. Okay?
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.
