Dreamless,
From what you have said, you are obviously not yet ready to leave your partner. I can sense the fear of him in your posts too, and there is NO DOUBT that he is extremely abusive and destroying your self-esteem.
I think you should start by taking tiny steps - PLEASE PLEASE PLEASE get some long-term counselling and hopefully you will start to regain a little confidence and self-esteem. There will be some issues inside you which are making you feel you must stay with this person, stay in the industry etc , and until they are resolved it's likely you will still feel stuck.
I was an escort for years - it has left me with severe PTSD to this day and I totally understand how you feel trapped. It is very difficult for those who have never been involved in prostitution themselves to understand how we do get trapped, stuck/frozen in just getting by day to day without getting hurt, and how we deal with being treated like an object day in day out.
I was also stuck in a less-than-ideal relationship at the time. For me it got to the point where the job was making me so ill - physically and mentally, that I just couldn't continue. So I went to a local project for women in prostitution (maybe there is one near you? they won't force you into anything until you are ready) and basically just FORCED myself to keep taking steps to get out and one thing I also had to do was throw out the partner. It was hellish at the time and there were many dark times, but I applied for benefits (and was a nervous wreck waiting to see if I would be entitled to anything at all), downsized everything, got a job, got legal advice against the ex, just kept on pushing through, attending appointments, doing what needed done, because the alternative was worse.
You don't sound as if you are 'broken' yet, you still have that fighting spirit in your posts where you are standing up for yourself. You know inside you are a worthwhile and lovely person in your own right. You just need to begin to take steps to really believe you are worth more than someone who clearly doesn't love you and a damaging job you say you hate, and start living life "as if", take baby steps until it becomes reality.
God knows it's not easy! but it can be done.
What would you like to happen? Is there anywhere you can go for support? (I can try to find out for you if you like), can you access counselling? (often sex work / sexual health clinics offer free and quick counselling, but also if you can pay it is around £40 for an hour once a week even if you could squirrel some away for that).
That's another thing - can you start saving up some of your earnings, no matter how small an amount, and keeping them well away from your H? Surely he has no way of knowing exactly how much you have made? You could say that one or two bookings a week were 'no-shows'? Ultimately if you want to get out (and you say you do, I think) , there must be ways of doing it.
PM me if you like x
Take care, and whatever happens don't feel you can't come back on here for support anytime x
