I have a friend who I used to see a lot of, even go on holiday with. Her daughter started school in September and, ever since, she's got no time for me (and my pre-school kids). She told me she's busy with new mums and doesn't like to turn any invitations down for fear of missing out. I gently told her that I've felt a bit hurt and I miss her. She said she was sorry and seemed genuinely so, but there's been no change. Maybe she's just not the friend I thought she was. To spare my feelings further, I'm best to just put my efforts into my reliable, true friends, aren't I?
