I totally agree w/"T" on this...they feel like they are on high overdrive w/anxiety. It's part of the MLC.

I'm glad you explained a little bit of what is going on w/your h to your son. He does not hate his son...however, right now, he may be jealous of him because he's acting about your son's age.

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.
