My brother has not been in direct contact with my mother since he relapsed three weeks ago. I haven't seen him in in a couple of weeks, but have been in touch occasionally by phone and email. My Mom sent my brother a holiday card and invited him to Christmas dinner with her and me. I just got an email from him indicating he didn't feel it would be a good idea. I'm fine with his decision; he has a complicated relationship with my mother, and I think seeing her (and probably me, too) makes him feel anxious and depressed - both triggers for his drinking.
I think my Mom will be sad, however, and that makes me sad. I'll be glad when this crummy holiday season is behind us.
