am i a bad person?

I love him so much and i want to be with him forever. but he can’t take no for an answer and it scares me. whenever i don’t take off my clothes or do what he want he get sad and nags me. he says he is. sorry and i say it’s fine because i love him too much to leave. he never does his school work and he is failing. he never takes care of his diabetes and it scares and worries me. we can’t have a good life together if he don’t grow up. all i want is for him too grow up and not control my whole life. i can’t even hang out with my friends anymore without him showing up. i’m finally making friends and he is going to push them away. i love him but i’m concerned. i feel like im a bad person with a bad heart for feeling this way.
