I have been friends with, who I thought, was a good friend for around 23 years. We met in college and lived together for around six years after college and had a great time. We both met our husbands in or around the same time and she moved away (but only about 2 hours away). We are both married with children and I now rarely see her but we keep in touch with messaging etc. She cancelled the last meet up and with Covid another hasn't been arranged since. I saw though that she has met up with a group, including someone from as far away as I, for her Birthday. I wasn't invited. When I think back she has been near me a few times over the last few years for concerts etc. and hasn't offered to meet.
Given that we lived together and have such a shared history, I don't think I want just a message here and there type relationship. AIBU to just want to let it go completely? it might focus my mind on meeting new friends if I was more honest with myself that the friendship is over.
