I'm an older (53 yr old) single mum with an only child who is 9. I have always struggled a bit with friendships and have always found it difficult to meet other mums but I tried really hard. I invite my little girls friends over at her request and include them on days out and trips to things but she is never invited back. I don't understand why or what to do about it. I feel like I spend the school holidays waiting for parents to reply to me, sometimes they don't even do that. I now hate the school run because I just feel like a div. Where am I going wrong? The playground is also very cliquey. I just don't get it. Help
