Girl.
What kind of "irl best friend" is this person? Like, if by irl best friend you mean toxic then I'll take that, but you should either confront them or just dump them. A good idea for revenge would probably be success, or show them that you're doing perfectly fine without them. That's what I do.

Honestly, it's ridikulus and disgusting how people can be.

Comment here if you support potions_master_394 so she knows she's not alone.
Yours Sincerely,
mE :D
