Well, my boyfriend & I have been dating for two years, so he's a regular around my family. I think they don't put his name *just in case* something happens, but leave it open for me to bring someone else should that *something* happen. I've never had to go to a wedding single (except obviously for when I was very young and didn't date), but I can just imagine how awkward that would be.
I did not intentionally offend my aunt. That was not my intent at all. My intent was to inform her, politely, that at 21 I would appreciate my own invitation to things. Does everyone really think that I sat here and said, "man, I'm gonna call her up and rip her a new one about this, she's such an idiot, I can't believe it, rant rant rant"? Because that isn't what happened. It was more like, "Hmm... shouldn't I have my *own* invitation at 21? Especially if I'm bringing a guest? Maybe she doesn't know that's how it works. I'll let her know for the future."
