I’m related to a few people like that and they are indeed all of those things and more.
I recalled this as I wrote the post and wondered if you'd read it and draw a parallel.
Cutting them out of one's life is often the only way. I've done the same, and will continue. There was a time or two I've persisted, tried to help but I've come to the conclusion that I just don't care about people who destroy others in a bid to self-build.
It feels great to draw that line and move on, refreshing, uplifting and energising. It's the only way; take the high road that moves off on a tangent away from the scum.
Yeah for sure! They like to text me and bother me around birthday times, since the little man and i’s are so close. Can’t enjoy the month, nor major holidays like the winter ones without them feeling like they need to bother me, despite the rest of the year not giving a flying fuck. It’s annoying to have to waste energy on it sadly.
When my wife’s friend said how great it felt to cut them out, my wife said to her “now do you see why we cut his family out? It’s liberating!” Lol
Them coming back on you, that's more about them than you I'd say, and a weight they need to carry at all times; the need/desire to keep circling back to where they are unwelcome. I'm certain you know how to deal with it, how to deny them any space in your head.
