my fuckass ex (tw; mentions SA)

my ex is a horrible person. he makes jokes about r*pe and even did that to someone once. i didn't know about it (obviously) because he seemed like such a great guy when i dated him. But recently my friend (let's call her orange for the sake of privacy) told me about him r*ping someone and that she knew about it a long time ago but "forgot to tell me" because she thought it would "ruin everything". 

i'm really pissed off at her for not telling me that because if i had know about him being such a bad person i never would've gotten involved. 

But now i'm questioning EVERYTHING. especially with the way he's treating his new gf (cheating on her, etc etc)

and also he's been flirting with orange a lot lately and she kinda just ??? lets it happen?? idk it makes me really uncomfortable knowing my friend is being flirted with MY EX. mind you, i loved this guy at one point. 

It's not like i can just stop being friends with orange. she's friends with my cousin (we'll call her carrot) and way closer to her than me. 

they keep reminding me that i dated him WHEN IT WASN'T MY FAULT BRO I DIDN'T KNOW HE WAS LIKE THAT. it was funny when they made jokes about it the first few times now it's just getting irritating. 

anyway thats it for now !
