bro 💀💀 if even completely sober you're saying the same thing about her then a possible spiked drink has nothing to do with it

to be honest there's nothing to save here, you made a speech in a room full of your friends and hers saying that she's not pretty, how would you react if she did the same thing ? that's some pretty bad public humiliation

as for the bad experiences with the "bitch queens" mate, go to therapy, that would maybe stop you from being an ass with other of your future girlfriends

and I must add : on top of the humiliation she must feel really betrayed now, cause I'm sure you told her that she's pretty, gorgeous, beautiful yada yada, and she just found out that it was all a lie, that you never found her particularly pretty cause you just can't get it up if that's someone you find pretty, I'd feel heavily betrayed too if it was me ngl

guess you're single dude.
