Attending weddings, With your boyfriend. Options

So, my boyfriend of 6 months invited me to go to his cousin's wedding with him in late October...
While I'm thrilled and honored, I am also incredibly wary.
You see, in my opinion I feel like this is something on the serious side.
After telling one of my really close conservative friend about this today, she was kind of skeptical and told me that she doesn't think it's a good idea. Mainly because it would make me seem like I'm a girl without manners?
I don't know.

If I go, I will be staying with him at his uncle's house (in the basement while his brother takes the guest room).
I'm Asian and my boyfriend is Caucasian so there's definitely some culture gap despite the fact that I'm a third cultured kid.

What do you guys think? Is this a big deal or am I overthinking the entire situation? Should I go or not? And what are some wedding etiquette that I should be aware of?

^ I thought about that but would that come off as offensive? :/ And if anything I might as well stay with my aunt, no?

Ok first of it's not that serious. If your mom already knows the details of you guys relationship and she is cool with you going, then what exactly is the problem? I think you're making it a bigger deal than it already is. Have you not been to a formal event before? It is pretty much the same protocol as if you were going to one of those.
