My Partner of 10 years has always been a heavy drinker .I've stood by him all this time , but in the last month his alcohol has increased to the point he is falling over slurring his words and telling me he wants the drink to end his life .I know I have to leave him , but he looks to me to help him like before but he's getting worse .He's not verbally abusing me ,but he picks faults with the tiniest thing I've done wrong like not hold his hand when we are in public .Then makes me feel awful and it's because of that when I try & end things he makes me feel I'm the 1 who will tip him over the edge .Please give me the strength to walk away & not feel the guilt .Thank you
