gotta agree with Shred on this one...
take your girl on your own trip. fly solo with the boys on this trip and fuck some shit up. Just because the other dudes do shit you're trying to get away from doesn't mean you have to participate. Unless they're fuckwads they'll be cool about it.
If your girl pitches a fit about you hanging out with the boys one week, then it's time to move on. If she's a cool chick she won't have a problem with you going solo.
