You are correct. If you stay with him and do for you, you are showing him that it's okay to put you through all that.
You are correct. It really is not okay to put you through that.
You have a choice:
1) you either stay and accept that him putting you through that is okay because ____ (fille in the blank with rationalization of your choice: he's sick, he can't help it, he will get better, he needs you, love can overcome anything, whatever...). Or,
2) You leave and show him it's not okay to put you through that. Or,
3) You stay and spend the rest of your life SHOWING him it's okay to put you through that but keep TELLING him it's not okay.
I don't think there are any other options.
