I recently read an IG post that said to delete the numbers of all the men who treated you wrong. If the act hadn’t backfired for me, I’d strongly suggest it. Except every single time I’ve done this, I ended up memorizing the number after seeing it on my screen so many times. I DON’T EVEN KNOW MY MOM’S NUMBER BY HEART. Dafuq.
Thus, I would suggest changing their name on your phone instead. “Fuck Boy”, “Asshole”, and “DO NOT PICK UP” seem to be popular. Or you can take the sad, but effective “He doesn’t want you” approach. Whatever you do, leave out any desired adjectives in his name. When you’re drunk or vulnerable, “Big dick bastard” will only read as “Big dick”.
