Throw away account because I'm not

sure what to do. I am 56 years old. I've been with my partner for 35 years and together we have two children, 17, and 19 years old. Our relationship is super toxic and I don't think it can be saved. We live in a house that my

partner inherited from her parents. There is a family business that operates out of it. For the last 20 years I have been running and been the principal worker in this business. I never wanted to do it but my partner wanted to be a writer so I worked so she could write. I was young, in love, and I believed in her. She never found success as a writer. She barely even writes. I knew that there was a chance that she wouldn't make it but I wanted her to have it. So I worked and tried to be the most supportive partner I could be. Eventually, her parents got sick and passed away (they were older parents). I am far from perfect and have made lots of mistakes in our relationship but now she pretty much openly blames me for her life not turning out like a fairytale. I've been grinding for 35 years doing things that aren't my dream so she could have hers. She contributes nothing. I work, do all the household stuff, while she abuses me verbally from the couch. She often hits me and always says just the worst things she can imagine to me. I don't want to take her inheritance or make things hard for the kids, but starting from nothing with debt and bad credit isn't appealing. If I leave, I will be jobless, homeless, and in massive debt (credit cards mostly in my name that she used to fund vacations or expensive things/experiences she wanted for herself and the kids) The family business brings in about $14k per month. We never have more than a few hundred in our bank account and the house is in bad need of repair. The stress of the business and my wife's awful behavior is killing me. (working 11-12 hours a day + domestic stuff). My health is okay right now but I can't even get a Dr's appointment or see a dentist. I need to get away from this job but being away from my kids would be the end of me. Sorry for the huge block of text, but I wanted to vent. Appreciate anyone who reads or comments.
