It's hard and it's scary, trust me I have been there.
I knew I had to leave I spent time stockpiling whatever cash I could I took all passports etc
I confided in my GP and he was amazing, he was the only person I ever told and he supported me.
The domestic violence helpline were my other lifeline and the samaritans.
The arse holes never ever change don't fall for their manipulation, they don't mean it and they certainly don't like people knowing what they are really like I was told no one will believe you but when he was slapped with a non molestation order, arrested he soon changed his tune because any abuse be it physical or mental is still abuse, the worst thing with emotional abuse is proving it, keep notes and keep safe, have a safety plan.
If you think you can't pack, tell yourself I'm packing for a couple of days I'll be back but don't come back.
I was absolutely prettified I would loose my children, I sat in my doctors offices snot bubbles the lot, begging him to help me escape as I trusted him and please don't let me loose my children and you know what I didn't, social services didn't even visit me, CAFCASS didn't visit either, you know why? Because I am a damn good mother despite what he said, people saw though him and they saw that I done all I could to protect myself and my kids, I told the school I was honest with who I needed to be honest with and I was supported.
It's scary to leave but living in fear of what he might do next is not healthy. I really feel for you. I got out and I am here to tell the tale
