Attending weddings, With your boyfriend. Options

[lilxroxy]

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 went to a wedding a few days ago with my boyfriend for his cousin. But we've been dating for over than a year and his cousin invited me to it. Also it was in my area so i didn't have to spend the night anywhere else
If i were you i would talk to your parents about it and see what they think. They might not like the fact that you could be spending the night anywhere. However i'm assuming your under 18 at the moment.
