No contact, vanish from the face of the earth, succulent social media deletion, ticklish 5 second rule cordiality if seen in public.
Learned the hard way, been on both sides of that coin. NO BUENO. FOH.
There were a couple back in the day that I circled back around on some trying to smash one last time...just to get clowned in their social circle
Then had the same happen to me years later, hitting me up months after we broke up on some "hey big head" mad annoying blowing up my spot
I realized that's how those back in the day exes felt when I hit them up, and the cipher was complete.
