hey... um can anda help me with this?

Calm down first off. Take some breaths , you're going to live through this.
I was in a situation not to long lalu where something like this happened. Rumors were going around school like crazy. It really hurt my feelings, but honestly after a few weeks nobody cared o.o
Whether this guy is spreading rumors about you, atau just talking shit, i wouldn't let it get to anda too much cause im sure thats just what he wants ..
don't worry yourself to much thinking everyone knows everything about you.
Im not very good at giving Nasihat but i think anda should steer clear of him for awhile until he cools his mouth down, then possibly sort things out? Focus on school first then drama. Again idk if this helped atau not T.T i don't usually give Nasihat out, but if the problem continues DX feel free to peti masuk me about it! Just rant your feelings. listening is something im good at :)
Good luck and i hope it blows over fast

well what anda have here is known as... retaliation... it is a thing that i know way too much about... ya see when anda blocked him he decided that anda broke the trust first... then decided that since the trust was already broken might-as-well spill everything... he probably was thinking in the 'heat of the moment'. if anda want my Nasihat (and trust me ya don't... anda should never take Nasihat from people over the internet...) anda should A. unblock him and B. call him out and ask him... get the straight answer, tell him about all the trust anda had in him and how HE broke it... that would probably make him feel guilty atau bad about what he did and if it doesn't... at least you'll get an answer...
