Need advice

I’m 17 my bf is soon to be 18.. my grandpa

Is letting him move in cause he doesn’t have good home like anyways. He got job awhile go. He tells me he got the job for me. He didn’t care if he had job or not before he meet me. When I say it’s his money he correct me say it are money even when I say it’s not. He ask me if I need money I’ll tell him no even when I honestly do then I’ll go and stressed about money. I hate when he busy is dinner I hate when he buys me something... i really do love him and want be with him forever but I feel so embarrassed and low when I need his money. All he tells me in he wants take care of me... Any thoughts
