A few months ago I cut my low value friends out of my life and I've never been happier (it's crazy just how much mental energy you get back when you no longer have to deal with their b.s.).
For years I knew this friendship wasn't working out deep down, but I kept the friendship going because at the time they were my closest friends and constantly tried to just look at the good.
But the clincher for me was when I asked myself, "Imagine the guy you could see them dating/ marrying one day. Would that be a guy you would feel comfortable having around your kids?"
And that answer was a huge NOPE!
(I was trying to think of a question for my childfree ladies. This was the best I could come up with so far: "Imagine the guy you could see them dating/ marrying one day. Would you be comfortable going on vacation with him and your friend?")
