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?

If you were getting married, that would be "serious". But merely going to a wedding with a boyfriend isn't that serious.

with some asian families (especially the traditional ones), going to any type of formal family gathering with a significant other implies one is willing to take the time to know the other's family, and back in the "olden days" that would usually only happen if there is a promise of marriage. even now, there are asian parents who think this is inappropriate behavior for an underaged girl, especially if the girl would be spending the night, god forbid (sarcasm).

do your parents even know you have a boyfriend? let's start with that.
