I did at one time, years ago. It had a change of clothes (neutral so it would mix n match), underpants, bra, nightgown, meds, makeup kit (I put 'almost finished' products in it), contact lens case/solution, toothbrush/paste, important documents & phone numbers. I had a 'fuck off fund' of hidden cash, too, that was where he would never look for it but was quickly accessible to me. I also made sure my keys and wallet with all cards were always in my handbag and that I knew exactly where it was at all times.
You and I are about the same age. Please, please don't waste any more of your precious remaining time on Earth with this waste of space. Better a pot noodle in a bedsit alone than filet mignon in a mansion with this man.
May I suggest that the next thing you need to do is see a solicitor? Have a list of household incomings, outgoings (yours and his) and investments, pension, etc. A good solicitor will be able to give you a good picture of what you may or may not be able to expect as far as division of property/assets/income goes.
You know, ofttimes the people in our lives are much more aware of our being abused than we think. It may be that your child, sister, brother, friend sees how he is and is just waiting for your phone call. Do your children have any idea of how he treats you? Can you confide in one of them? Do you have siblings you can speak to for support? It's time to reach out for support.
