How to cut all ties

[Angelik]

I need to leave home, house, family. How do I do this?

You’ll need to expand, are there kids involved, do you own your own home/work etc

More info needed. Do you own the house, are you named on the rental agreement, financially how are you linked? Children and ages?
Do you have any support network?
Job one is legal advice. Some do a free 1 hr appt. 2, see if you are eligible for universal credit or other benefits and apply as it takes time, set up own bank account if not already done. Get copies of all paperwork, abd get passports etc and stash outside of the house in a safe place. Save every penny you can secretly.
