<human>: My boyfriend (Jack) is in a fraternity, and some of his fraternity brothers are planning to go on a 12 hour road trip to NY in order to visit a fraternity chapter's party there. Jack says that the parties they throw are huge-- up to hundreds of people. The thing is, I'm very uncomfortable with that. 

I'm not going to lie and say that it isn't partly because it's a Halloween party, where there will be tons of girls dressed extra promiscuously. That is, honestly, a factor in this. The fraternity is also an asian fraternity, so there will be loads of asian girls there. He told me before we were dating that he has a "thing" for asian girls. This makes me even more uncomfortable (and, I'll admit, insecure) about him going. Yes, I know that this is not a good reason to ask him not to go. I'm being insecure, and I need to trust him.

However, I am also a huge worrier. I get anxiety, and I overthink things all the time. I know that if he goes, I'll worry about/through the whole 12 hour drive up there, and the 12 hour drive back down. I'll also worry that he's going to get drunk or high and do stupid things at the party(he is notorious for doing dumb things when he's drunk). This bigger the partier, the crazier they are. And people seem to go to those parties to just get wasted and laid. These are the main reasons for why I'm uncomfortable with him going. There may be other reasons that I just can't pin down.

He knows that I'm uncomfortable with him going, so he hasn't said for sure whether he's going or not. He says that he really wants to. When he asked why I don't want him to go, I said I'd tell him later, when I'm done studying for my tests.

Basically, I want to know if you think that I'm being unreasonable by being uncomfortable with him going. And I want to ask for any advice on what to tell him tomorrow.

Could you distill the essence of the text into 1-3 sentences?
