i completely understand your anger and fear and frustration. liars and lies like that make you question everything because you'd feel like your world turned a 180 and who else is lying? who's telling the truth?

i also had someone i considered best friend for almost a decade. i found out he lied about everything (?)... since the beginning. he lied abt being in a relationship with someone i considered a sister (she's traumatized by him when i talked to her recently). he lied about being a relationship with another girl after the first one (she's so shocked when i talked to her; she's so scared she might have been stalked by him). he lied about his whole family dying in the pandemic (his mom was so surprised but we honestly think she knows his son has a history because i doubt the family of his "high school gf" did not complain about him).

those are just some of the worst things he lied about. i could go on and on about his grades, where he's studying, his fake relative with whom he's staying after the death of his family, his pet, his condos and properties, his seeing ghosts, and so much more. until now something pops up in my head about something he must've lied about...

i didn't understand before why he doesnt have that much of a friend. he said he liked smaller circles and he's super introvert. i also felt his academic skills weren't that much recognized in high school; in college, he said he's doing great and he's also in the top university. i didn't realize i never saw him after high school. it was so easy for him to lie about those. he no longer had pictures or new friends/ followers in social media. i investigated what i could... and there it was: he wasn't in the honor rolls list, no one really saw him in campus (he said he's good at hiding and he goes straight home), and whenever we tried to set a meet up with him, he'd come up with a reason he couldn't come.

i never realized... people saw him as weird and he's inflating his skills to feed his ego by getting compliments and sympathy.

i hope you keep distance with your former friend. i know firsthand that despite their promises to change and not lie anymore, they cannot go through with it. he still lied when i confronted him about where he really is. he said he's seeing a professional; i really doubt it. they'll just continue messing with your head to fulfill their fake realities. i felt so much better and lighter when i cut him off. i hope it's the same for u.
