My question is: how can u love a drunk? A drunk is obviously a person whose mind is out of order, whose feelings, decisions, behavior and acts are subject to something that controls him 100%. which means that what he has become us not his real self but a sort excuse for it. So I wonder, it cannot be him you love but just the fact that being with such a person makes you feel needed...it's called the Florence Nightingale's syndrome

this man needs ti be cured by real doctors not by someone who just needs to feel important. So, make sure he gets treated properly, and then once he'll be back to normal you might evaluate if he can be the right man for u.
