HI NewHeart,
Sorry that you meet someone special and they flipped out on you. You are not stupid for opening your heart to love. If you don't open it you will never find love.
You are correct in deciding that it should be over. I know it hurts to say that its over to someone you care about. But yourinstinct from everything you have learned here kicked in and gave you the strength to do what you needed to do.
I know you want to fix him and get back the person you fell in love with. Just like an alcoholic he has to figure what is up with him self. You can only tell him how you feel. The rest is up to him. Keep being strong and coming back for advice.
