I'm questioning my friendship with my best friend
What's making you question the friendship?
I feel my friend is too restrictive  and I don't respect him anymore.
I'm sorry that's happened to your friendship.  I think it'd be better to try and talk this out with him though, right?  It's better to work out your conflicts with others rather than just give up on your relationship with them.
Nah, I love drama and this is fantastic.
You may well decide that the friendship has run its course, but it's rude to end a friendship poorly just for the drama. It's much kinder to try to work it out or at least communicate with your friend.
