Hi, letgo, welcome to PsychCentral (PC).

What does your family say about your life? I would borrow money and get as far away as I could from the man and stay there; nevermind that he is sick; that's his problem this time. You cannot live like you are. Move away and make sure you don't ask after him, how he is or isn't doing. If he has family they can take care of him if they want; you don't want to because he isn't/hasn't treated you well. You owe him nothing!
