You CAN get the financial support without the abuse! My SO supports me financially - I live with him, so he pays all of the bills. He pays for my car insurance, my pets' food and vet bills. He pays for my car to get fixed and for gas. He buys clothes for my son. He has offered to pay my car payment, but thankfully I've been able to pay for that. My health insurance is through the state, and medications through the county.
AND, he expects nothing in return. I do cook and clean and do whatever I can to make him happy. Including in the bedroom - but that is because I LOVE him and I WANT to! Not because I feel pressured or guilty!
It IS possible. I never believed it was possible until it happened to me!
