What you do if your partner wants to live rent free?

So I bought a house and my boyfriend asked could he stay with me so I told him to give me $500 a month and help with groceries. He felt it was too much and he has money and he still lives with dad without paying anything, he gave his dad $10k and that was it. I told him if we were married it'd be our money together.
