4mylove,
I think Carla said it best. Love him, pray for him, but get on with your life. You cannot control how he is, only you.
Go out and make friends, volunteer, have fun. If you believe in God, trust Him. Give ths problem to Him and let Him deal with it.
Since you cannot do anything about it, do not let it eat you up.
I have a prayer on my wall it says: God give me the serenity to accept the things I cannot change
The courage to change the things I can and
The wisdom to know the difference.
This advice has done well by me. Some things are beyond our ability to change and we just have to let it go.
My heart goes out to you. I used to live in fear too. It hurts.
Love and hugs,
Velta
