When should I ask why I wasn't invited?

So my roommate and his cousin are throwing their "biggest bannger of the summer" tomorrow and my roommate didn't even invite me. We were talking about what we've got going on this weekend and he mentioned that last night and was telling me about one person that's supposed to maybe be there, then this morning I heard about another person I kinda know. I'm sure his excuse for not inviting me is going to be that he knows I'm not a fan of that type of environment. Being that we're roommates and I'm supposedly his bestfriend and he knows I don't have friends around / have trouble socializing I'd hope he'd at least think about inviting me. So whatever his reasoning is I'd really like to hear it. Not sure if I should ask him before it happens, or after it has happened when I ask how it went?
