Background: am a lone parent with dd. No family within 200 miles, and both of my parents are long dead. Have come to view extended family in the area (a cousin, her dc/their dc) as our 'family'. DD thinks of this cousin has her grandmum (and cousin refers to this relationship in same way), and cousin refers to me as her 'sister'.
Fast forward to this past weekend: there was a big community event at the park near our house. I arranged to go with friends and their dc. As we were sitting to eat our picnic lunch, dd comes running up and announces that the entire extended family is at the park, with a MIL along, and another family/their dc.
I was completely gobsmacked that this gathering had taken place without anyone in my 'family' calling to either:
a. Invite us to join them (clearly it wasn't last minute as MIL and friend were there with them)
b. Tell us they were going to be there, and hoped to see us there
Nothing. Cousin's dd came over and I could hardly speak I was so taken aback. Cousin's ds came over and I blurted out something along the lines of 'why didn't all of you let us know you were going to be here'? He mumbled an apology, looked a bit embarrassed, and after an awkward conversation - left.
Turns out they were all leaving as they had been at the park since 10AM (we arrived around 1.00). As I was finishing lunch with my friends, saw my cousin walk to her car and drive away. She never came to speak. Since then, no contact.
The ironic part is that if they had chosen to meet in the park near my cousin's house, I would never have known about it and wouldn't have bumped into all of them.
I don't feel this can be ignored, but don't know what to say. I feel completely disregarded, hurt and rejected.
Any advice would be gratefully received.
