My friends with benefits tried to hit on my best friend?

Anonymous
So had a friends with benefits situation, I don't have feelings for him but i got a screen shot of him trying to hit on her on Fb. I at first told him I thought that was crossing some lines, that idc who he sees but close friends are just disrespectful. He told me "you don't own the bitch or me" told me to "stfu" and flipped out. I'm DONE. Am I overreacting or is this really some boundary crossing?

So done w this guy, I knd of feel like our situation needed to end along time ago, its been going on 3+ years. We have been good about communication, he knows if I see or talk to other people and vice verse, so it made me upset he went behind my back to get at her, knowing that's my best friend who is engaged. Plus now that this has happened, he's showing a whole new side of himself that I don't like. He is texting non stop about "so what yo don't want to see me' and blowing my phone up. So done
