Friend dillemma/dev tickets involved

Somewhat Dev related. If this is wrong for me posting, I'll understand
So a few months back Dev tickets went on sale for the BTBAM tour, and my friends knew I wanted to go, more importantly that i was going to drag them along with me. I purchased 3 tickets, one for me and 2 for my best friends, Jim and Dave.
here's the problem, my best friends don't exactly get along. one hates the other. They both have acknowledged that they were invited and the one friend Jim has been cool about going, however anytime I bring up dave's name it's like "screw him".
These guys used to be friends before they were friends with me, and there is a whole back story behind it, but now I feel I'm in a shitty place because all I wanted to do was share a live experience with my best friends, and now it looks like i'm gonna have to exclude one of them. Jim isn't really one to be reasoned with on this, he's told me a billion times he never wants to deal with Dave again. Dave on the other hand doesn't really understand how he messed up with Jim.
What do i do?
