My own wisedom:
Alcoholics , and this is rare - are only able to see the severity of their situation after losing things that are important in their lives and your leaving may awaken them to how serious their problem is - rats will never correct their behaviour.
Don't be worrying about me, I'm just a softhearted, sensitive wazzock.....it still really upsets me when people like UKlady gatecrash our little safe space with hostility.
Note to self: Toughen up, you softhearted wally!!
