So I went to a really nice resturant about 6 week ago, while there my dm rand me and I said how nice it was and that I wanted to take her there for mothers day. She said oh that would be lovely.
A couple days later it was mentioned again and again she said it would be lovely.
then she said she wants to see her mum really as she's probably not going to have lots of mothers days left, which is understandable and then we made firm arrangements for the Saturday before.
Now she's just rang me to say my sisters taking into town for lunch. I'm actually really upset that she's going out doing what I wanted to do with her.
background info my sister was always the golden child and firmly my mum's favourite growing up, I left home early and it's only since I had dc myself that me and my mum built back a relationship 6/7 years ago.
Sorry, but I think you are being oversensitive and a bit needy. You are an adult now with your own child and should have grown out of this sort of sibling rivalry for your mother's attention.
Your mother obviously does love you and she's there for you when you need her, as she is for your brother and sister. She also has her husband and elderly mother to consider. Why should you and your dc be her main priority?
