We heard on Christmas Eve that two of our friends had split up. At his instigation. She is very volatile and drinks too much. I have posted here about her always being drunk when she turns up here and how it upset me. I didn't contact her before christmas for purely selfish reasons - I have had so many weekends taken up with her problems and to be frank I am worn out by her. I didn't want our precious christmas ruined by tears and misery.
I texted her to say hello and ask jer how she was doing late on christmas day. No reply.
I know it would have been the generous thing to do to invite her here but I felt I owed a peaceful happy christmas to my family (and to myself).
She has 2 grown-up DDs and other friends so I don't think she would have been alone but it makes me a crap appalling friend doesn't it 
I wish I had happy stable friends. Most of mine seem to lurch from one crisis to another and DH and I are boringly stable. I sometimes think that is why our friends like us.
