It sounds that perhaps he is using you for money. It seems a bit extreme that he is ok living off a woman and playing house on her dime. Honorable men would get their life together first and live with it roommates/fellow classmates/ family, not with a woman who is willing to support them.

If you have extra money I am sure you can find better use for it. If you want to keep dating him you could but he needs to live elsewhere.

I really can’t imagine a guy moving in and treating me bad and refusing to help around the house all while I am supporting him. It makes no sense. Why? He needs to move out like yesterday. You need to love yourself more
