just sending you some words of support there; any chance you get do try the helpline, or you can register for texting them. All the planning in the world won’t matter if you suddenly feel you need to go then you need to go and don’t look back.. You can turn up to the police, or phone them from wherever you are and tell them you fled your home because of your fear of him as you need it to stop.
but in the meantime, maybe you could have some stuff stowed away. passports/birth cert/utility bills/mortage/rental bank statements. some essentials, hidden away just in case.
I’m terrified and i think you are very brave to still be there, i’m scared for you, its weird isn’t it, seeing it from the outside!
be safe and happy. its all that matters xx KS
