How to make an exit plan?

[PaperDreamsHoney]

I've accepted that my marriage is really unhealthy for both me and my kids and I need to make a plan to get out, but I could do with some advice. (For background, previous thread here: www.mumsnet.com/Talk/relationships/3770110-Is-it-awful-to-want-to-split-just-because-Im-miserable

I got married very young and my husband didn't like me working, so I have no career to go back to. I have good A Levels but no degree (working on that atm). Realistically I might end up on UC for 2-3 years while I finish my qualification, then I'll be able to get a decent job.

Right now I know that I need to be trying to put money away for when I do leave so that I can pay a deposit on a place for me and the kids. I also need to widen my social circle because I have no family to support me and most of my friends will want nothing to do with me once I leave.

What else do I need to think about? I'd be really grateful for any advice.

Evidence of his finances if you can but I know that can be contentious. Even if it's just to know if he has tried to hide stuff.
Having a backup plan if he gets wind of it and forces the issue. Where could you go?
Similarly making sure yours and the kids key documents are somewhere safe outside the family home so you can't have to leave without them. My stbxh kicked me out and kept the teenage kids with him. I was then trying to get my DD to find a brightly coloured piece of paper with my name on and my car reg just to tax my car and keep working as he had decided what I could and couldn't take.. Don't make that mistake...
When you say unhealthy do you mean abusive and or coercive? If so maybe work on your own strategies and go to something like the freedom program if you can locally to build support.

There's some detail on my previous thread here: www.mumsnet.com/Talk/relationships/3770110-Is-it-awful-to-want-to-split-just-because-Im-miserable

But essentially it comes down to controlling behaviour that's validated by the super-religious subculture we belong to. I am seeing a therapist and doing my best to work on myself. I will look into the Freedom programme, thank you.
