I soo feel for you. Like yourself I too had to make an escape from someone I thought I knew, almost 7 years I lived with him and as each year that went by it just slowly got worse and worse and I didn't realize it until one day all I could do was think about stepping in front of a BART train on my way to work.
Thankfully I had wonderful supportive family and my best friend who helped me out. Like yourself, I just came home from work one day he happened to be out of the house, packed all my stuff, my parents showed up took my stuff and my cat and I jumped on a plane to England. That was 18 months ago.
Since then I fell in love with my best friend, got married, moved permanently to England, had our daughter and here I am.
Best of luck to you tonight, I'll pray for you always.
