Honestly even if you do think it would be better, I personally wouldn't ask somebody to move. Moving is basically uprooting your life and moving it all somewhere else. Your job, your friends, your home, your car, whatever. Obviously I don't know your/his situation, but in general yeah, it's his decision if he wants to move. I don't think anybody else should have anything to do with the decision (unless you guys lived together obviously, but by the sounds of it you don't). But that's just me.
As for what's bothering me, trying to plan things for two days away when people won't answer me. If you don't want to answer then I can't go because I have other stuff, so don't get pissed when it's the day of and I'm not there. ;l
