Working for free

Husband is working for free. At his best friends restaurant. Not getting paid always complains about money. We don’t even have nice things for our marriage. We live in an RV. We don’t even have a good water heater and he says it’s to expensive literally $300 for a decent one. He doesn’t take me out to dates I’ve recently gained weight. He doesn’t treat me the same it’s a whole mess. My anxiety and depression is getting worse and I feel like human garbage 🗑
