You're unhealthy bc you need time space and distance before you heal. You're currently in denial bc you don't want to believe things are the way they are.

Looking back, before I moved out, and this was something I knew for months it was over but I needed him to not know or I'd be homeless, oh man. Do I continue giving him sex and feel like a piece of me is dying each time by knowingly letting this man I loathe have me in the most intimate way or just say no? How much can I avoid without putting myself in a precarious position?

Know this: sometimes we get by and we survive by doing things we don't want to bc we have to. I didn't want to live with him or sleep with him or anything with him. But I didn't have much choice. I avoided sex for awhile but it became an issue. Fights happened and I've never given him makeup sex but he kept trying! I would say no I can't do it. Sometimes I drunk enough to just view it as just sex but I couldn't enjoy it.

You need to do what you have to be safe.
