Similar happened to me after an intense 8 year friendship that started when we met at a mother & baby group.
I was saddened when she cooled the friendship drastically. Initially I tried to meet up or invite her to things. Then I just benignly hovered on her social media and a year or so later I noticed she had unfriended me.
I recognised that we didn’t have much in common. Put simply she was very organised, healthy, energetic, motivated and ambitious. My life was rather chaotic, I couldn’t drive, I was unhealthy, skint and prone to being late to things we’d organised. So I could see why I’d piss someone off, but I like to think I was good company and supportive towards her.
10 years later my daughter and her daughter are 16 and end up going to the same sixth form college. Of course they get chatting because they remember so many fun times together.
I reached out to her via text, largely out of curiosity, and she appeared happy to hear from me. Messages went back and forth as an awful lot has changed for us both in the intervening years.
We are only friends on facebook but do comment on each other’s posts. Our daughters will chat if they see each other out and about.
I think it’s interesting to consider the longevity of life. I was so hurt by what happened, however I don’t think she could have ever envisioned that our daughters would circumnavigate her unilateral decision all those years ago and reconnect us.
I’m well past wanting a friendship with her now.
I’m a loyal and nostalgic old bugger who likes to hold on to friends. However if I were you I’d leave your friend to her own devices and invest time and energy in other friendships.
