Jail house relationship

I don’t know where else to turn because I’m so trapped in the relationship that I’m in and I’m scared to tell anybody what’s actually going on. My partner of a year has got complete control over every aspect of my life. He doesn’t trust me one bit so when he leaves the house all the windows and doors are locked so I can’t leave or let anybody in. He accuses me of sleeping with absolutely everybody he knows and puts me into a corner and I feel so helpless. He showered me with love at first and made me believe he was my soul mate but now I am actually scared for my safety if I tell anybody or I try to leave him. I am very vulnerable and alls I’ve ever known is abuse. He knows that and has taken so much advantage out of it. He has slight brain damage from a accident he had when he was younger and when he drinks it’s like living in hell. Most days I don’t even get out of bed because I am that depressed and miserable. He’s always working and never has time for me and when he does want to do something I’m that drained and tired that I don’t want to move. I am having therapy and have been working on my self and trying to be a better stronger person. But he makes me so sad that I feel like I don’t even want to live. I can’t reach out for help I’m not going to get into why because i don’t want to be judged by anybody I can’t take any more hurtful comments towards me I just need some kind words and I don’t know some prayers maybe that there will be light at the end of this tunnel. Please no nasty comments I just want some love light and peace sent my way.
