Had a good chat with Anne over a few glasses of wine a couple of nights ago.  She had become  a bit annoyed because, basically, I was not pulling my weight.  In particular, I rarely took the kids anywhere by myself so that she had a few hours child-free.  I can't say she was wrong and will do better.  Just talking about it has made things much better and we do need to communicate better - but isn't that the case with most couples?!!
