My partner stays with me 5 nights a week. Should he pay for utilities and food?

Dear Quentin,

I’m disabled, 52, and have one minor son. My boyfriend has his own house, and also has a minor child still living at home, as well as another son, 24, who is living at home and is employed as his younger son’s babysitter.

He stays at my place, probably five out of seven nights, but doesn’t seem to think…
