i want to confront him because its causing issues for mutual friends and i dont think this needs to be a "choose a side" type of deal.

He's acting like a baby. I would say one final thing to him... "We came to an agreement, we sat down like adults, you wanted this, I wanted this, we acted like adults and now you're ruining our friendship... I can forgive you up to this point, but no more from now on or we will no longer be friends or socialize, at all!".
Not defending him at all, but it's tough to see an ex flirt and be happy... Even when you're done, you want to move on before them and if they move on first, it's difficult.

I think he probably still could have feelings for you. Or he just is making drama, and tell him your not trying to make him jealous your accepting to be friends and if he can't do that then its better not to hang out with each other. Hopefully he will understand.
