First, the GAL is for you. Do things that make YOU happy. Do not put your happiness in the hands of another.
It is OK to feel sad. It is OK to feel how ever you feel. Feel the feelings as they come. I know I cycle through all kinds of feelings.
Spouse does not like the way you are interacting. Do 180s in the interactions you do have.
Face your fears, otherwise they will become true. Set him free and show him a happy, friendly, kind, compassionate, attractive confident women he would be crazy to leave.....Work on this while he is away. Practice with other people.
This is a great opportunity for personal growth if you take it. Want a closer relationship with your family, open up to them.
