I ghosted a friend who became far to needy and dependant on me, friendship needs to be a balance, but everything was all about her, and most conversations involved her moaning about how terrible her life was, and how it was everyone else's fault, or slagging off mutual friends, who she would then be nice as pie to their face to - got me thinking she was probably slagging me off uphill, and down dale as well, and I just couldn't handle that level of 2 faced. Every time I came away from being in her company I felt emotionally ground down.
Ghosted a friend of 20 plus years, was always there for her but when I went through some serious rubbish times, she never so much as messaged or sent a card (bereavement) I looked back over the friendship and realised just how one sided it was, she was a very me, me me person and if you'd a cold she'd a broken leg type thing, it was like playing a woeful game of top trumps.
Ghosted a friend who sent me the most unbelievable insensitive message of condolence, that included accusing me of ignoring her at a party we'd both been at a few weeks before I suffered the bereavement, and saying how annoyed she was but none of that mattered now (I hadn't intentionally ignored her, and she hadn't come up to me either, but she seemed to miss the point)
I now surround myself with positive people, I've no room for negative, emotional vampires, and fake in my life.
I was still sad to let the friendships go, initially, but a huge weight has been lifted from my shoulders, life's just too short.
