I had a best friend from when I was 5 all the way up to 25 years old. We're now 50.
She did something I considered appalling at the time, basically accused me and another friend of either impersonating her and/or stealing benefits from her, I don't know if the other friend did do this. Anyway, she more or less believed her then boyfriend who said 'Gonna doesn't have the bottle to do this', she rang me at my then work to scream down the phone to me, we met up and she then screamed at me again and we then broke up our friendship.
Since then she's done better than me, got married, gone to uni, started a business with her DH etc. She has, as she said to me, matured a lot and she's not the same as when she was younger. She came around to my mum's house one Christmas (just after) where I was staying at the time and wanted to see me - totally unannounced and I got angry and told her to F off. We connected on FB and were in touch for a bit there and sort of healed things. However, I've never had (and don't expect) an apology from her accusing me of stealing from her. She also said some pretty nasty things to me after our friendship broke up when I stupidly rang up, alone etc. I got other friends after that.
Over lockdown her mum died and there was drama around this in her family, I sent her a sympathy card, sent money to the charity her mum wanted for funeral and sent friend healing crystals. We kept in touch via text. But I'm really unsure as to if I want to see her/be friends more than that. Especially with no apology. She did have a hard life growing up and was a single mum young (at 18) too. She was my best friend and I know my mum had a big influence on her life (giving her books to read etc).
I'm just wondering, what would others do? I sort of feel like I've done the right thing and then sort of don't feel like I did the right thing. I deliberately haven't given her my home address as I don't want her calling around out of the blue either.
