I've decided that 'reading for improvement' will include books about spirituality and assertiveness, creative self development, parenting and meditation. But I'm not going to read relationship or marriage books any more for the time being. There might be a time for that in the future, and there's plenty about my communication I can improve outside of my marriage - but I think the obsessive reading of relationship books was keeping my focus on a relationship that isn't there any more, rather than on myself. I have made myself a little reading list (because apparently INFJ love a bit of order and structure!) this afternoon, which was a nice way to spend half an hour.
