I read somewhere that alcoholics are like crabs in a basket. As one climbs out the others try to claw it back in.
I had a friend like this, and just avoided her for a while. Then when I made contact I suggested places and activities to do that were nothing to do with drinking. She's often happy to do these things, but I can't expect her to think of them and be the one to suggest them. It's just not how her thinking is, as she still loves the drinking lifestyle that I have turned my back on.
Some people, it transpires, weren't friends as such, merely drinking buddies. This saddened me for a while, but once I'd got some sober friends I got over it. C
