If you don't like him except for "friends" why would you even consider damaging your relationship with your friend to go to prom? Go by yourself, or with your best friend.....you might also tell this guy that all three of you can go together as friends, other than that, I'd go by myself.

Not a good idea. Your BFF is never going to understand, if you value your friendship you should turn down that invitation to the prom.
