How to seperate with no money, feel so trapped

[Longingformore50]

OK so I'm 100% I want to seperate from my husband. Been together a very long time, have 2 kids. We have tried to work on the issues that have been going on for years and it doesn't work. Now at the point of no return I feel.
I have been a sahm for 10 years and just worked in a call centre before that on minimum wage. As many women have done (big mistake) I have stayed at home & took full responsibility for house /kids while husband climbed the ranks and is now a decent earner. Not massive but we manage. Ive been longing to go back to work for years but he didn't want me to as he likes me doing everything. He basically told me he wouldn't be available for any childcare ever so I wouldnt be able to cover the 13 weeks school holidays myself & I also couldn't pay for childcare and he refused. So I am trapped.
He isn't controlling with money, I can buy whatever I want etc, but he has controlled that I can't work. So I have no money of my own. I've told him I'll get a work from home job to make things easier but he said the money I would earn would have to go into family pot so I still wouldn't be able to build up any savings of my own.

Now on top of all that is the current economic crisis with the huge electric / gas bills etc and I feel like I can never, ever seperate from him. And it's making me feel trapped, isolated and desperate.
We own our home, he pays all the bills etc so he couldn't possibly leave as wouldn't be able to afford to run two properties until I can take over. I can't bare the thought of separating but still living in the same house, that would just be a million times worse than now.
If I just go for it and push to do it I obviously will have to work (no problem) but I won't earn enough to even cover the bills and I would have to claim universal credit to top it up.
I can't believe I've allowed myself to become trapped in this situation. In a life I don't want. My choices are to stay with him to get the bills paid & be desperately unhappy. Or seperate, and struggle to pay the bills and provide for the children. I can't believe I've got myself into this situation

im trying to leave my husband and he has taken all the money and I’ve been trying to get out, but I’m struggling and stressed out.. I don’t know what to do I’ve been feeling like I’m about to lose my mind, he took my passport and hid it from me, I think he has people spying on me too, I think he’s doing something else to me too, he took all the money out of my car I had and drained the savings account, he searches my stuff and car all the time. I was trying to find resources to get out of this situation, I need somewhere to stay, he pretty much cut me off from my friends, scolding me for just going somewhere with a friend like to a restaurant down the street. I think he’s got a hold on me, even had me thrown in the mental hospital and jail. Yep my whole family is lying about me… they are basically holding me hostage by keeping the marital assets away from me.. trying to keep me in this situation…
