I've been friends or so I thought with this woman at my kids primary school for about 3 years. Two of my sons are the exact same age as two of mine. For the first two years our sons did joint birthday parties. Last year she decided not to, didn't give her reasons and didn't invite my son to her son's party. The same happened this year. We have invited her son as both years we did a picnic in the park for loads of kids and to leave him out would have been mean. A few months ago she announced she and her partner are getting married and it quickly became apparent we weren't invited. I know weddings are really expensive but I don't know what we have done to be dropped quite so comprehensively and it annoys me that it has impacted on my son. I'm also cross because she is a psychologist and I feel she should have more awareness about the impact of her behaviour. I have years ahead of being at the same school so probably need to find a way if addressing it with her. I should add as a family they are considerably better off than us and I slighty get the impression we aren't quite smart enough as a family but i may be bitter and twisted!
