Yep. I have been ghosted. Don't know about orbited, I don't pay that much attention. I haven't done it to anyone else.
But I have done the ghosting sometimes, and always for a reason.
Sometimes it was because with certain people, there was no point in discussing the issue. There are times when you know they won't hear you and it'll be a complete waste of time and energy.
A few other times it's been because I did talk about how I was feeling about the distance - more than once - and nothing changed.
There are others - many others over the years...the people who were never the ones to reach out and say "hi, how are you doing?" Every conversation or visit was always initiated by me and after years of that, I stopped reaching out. They never bothered. Fine. I'm done.
And then there are the ones who I thought were best or very dear friends, the ones who were happy to have my support and encouragement, until I'd be going through something and they were nowhere in sight and didn't want to talk to me - because they needed me to be the strong one.
And sometimes because we just grow in different directions and one day you realise you don't resonate with someone anymore and there's no point in making a big deal about it; you just move on.
I do think it's weird, though, if in any of those cases you then "orbit" someone! For me, if I'm done, I'm done, that's it. I'm not wasting my time or energy on anyone or anything that doesn't feel right or contribute to my life in some way. Hmm. I feel an article coming on :)
