I ended a very long friendship (35 years) around 4 years ago. I won't go into all the details but I 'ghosted' her after she lost her temper with me one day and followed it up with a horrible email. She made a few attempts to contact me via text but never with an apology for how she'd behaved. There was more to it than that, mainly I felt she'd become a bit me, me , me.
However in some ways I'm regretting not forgiving her and feel maybe I was too harsh. I've had a hugely stressful couple of years- parent dying, close friend dying (who she knew too but doesn't know about their death), husband with serious health issues , and she is the one friend who knows my history and family more than anyone.
She lives an hour away so it's not likely we'd ever bump into each other, or have mutual friends.
I'm open to trying to heal the rift and thought a card at Christmas might be the way- but what to say? Would you say I should say' Thinking of you' of go as far as saying sorry and get in touch if you want to?
She may not want to, and if we resurrect it, the same fall out could happen again but I'm aware of that.
