I agree w/Cadet. Choose one or two very good friends that will be supporters who will listen and be there for you during this time. If you tell everyone, it will make it harder for your mlcer to come home, if he should opt to do so after his crisis is finished.
I have found that the more people you tell, the more drama is stirred up and continues to churn and then it becomes he said/she said. You do not need any additional drama in your life right now. Keep your friends close and share only w/those who know how to keep your information within your close circle.
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.
