Can You Just "run Away" From A Spouse? [ny]

I think the answer is 'no', but I'm trying to gauge what's legal and what's illegal regarding something that's a pipe dream of mine.

Can you just "run away" from a spouse with no or minimal legal repercussions? Are there good resources on how one would legally cut all contact with, and basically completely hide from, a spouse? I'm envisioning this something like a DIY version of "witness protection" - basically a way that he can never, ever find me.

A bit of context: I'm in my mid-30's, with an abusive husband (physical, verbal, sexual). I'll cut out all the details; but I'm convinced that if I try to leave him, he will track me down and hurt me. In addition, he refuses to work (he only works a very seasonal part time job), and so I would need to pay him alimony if I divorced him (I pay for our mortgage, and basically everything else). After ten years of marriage, I've drifted away from family and friends, so I don't have much support left there either - we just have our pets, who I'm very afraid he'll kill/harm if I try to flee.

I'm wondering if it would be feasible, or even legal, to buy a small cabin in a very rural area that he couldn't find me and essentially drop off the grid. I could save up some money and retrofit the cabin with solar panels, etc., change my name, bring my pets, etc.; and then get some sort of non-industry job (because I work in a small industry) where I can send money to him for alimony through a third party, and that he couldn't trace back to my location? I'm sure there's so much I'm not thinking of, and that this is such a pipe dream, but I've tried to get help through DV shelters and that went nowhere (it actually put me in more danger). I'm most concerned that if I just move states, get a new job, etc. he'll just find me - through my name on something like spokeo, alimony payments, etc. - and he will kill me.

Thank you in advance for any help or suggestions.
