I'm sorry that things are such a mess. I'm glad to see Dick has lost it w/someone else. I hope that this woman will be there for you and your son. It's a very sad situation and one that has scarred everyone involved. Your d is a lost soul right now and it's going to take some time for her to come to realize what has happened. I'm praying she will wake up soon and see the situation for what it is.
Some day, you'll have those picnics once again.
Please take care of yourself.
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.
