Hi pet, glad you made the call at least
I know where you're at, it's because if you leave, you're admitting to yourself that he really has done something unforgiveable, and that will open the floodgates of the built up fear and anger about it all, from however long ago he started making you afraid
That anger is terrifying to face, you will feel like it would never stop if you start to feel it - the feelings could be overwhelming and you might feel out of control, as if you could kill him etc.
But the thing is if you don't face it now, there will be even more of it to face when you finally do leave - if you leave, that is, because this man sounds as though he could quite easily kill you.
Sorry, that is a bit harsh of me to say but it is perfectly true.
Gather support, your friend etc and WA and have that network ready when you want to leave.
The more people on your side, the easier it will be to go.
Making the break in your head is the first thing - realising that you don't have to e with him, nobody is making you stay, nobody expectes you to.
You don't have to love him. No court in the land can make you sleep with him.
You need to harness that anger and it'll get you out.
Be brave, I wish you some peace tonight but for Gods sake don't stay long enough for it to happen again.
