Note: This isn't recent, I'm still not sure wtf to do, nor do I inderstand either of them.
So a couple weeks back, my girlfriend introduces me to her cousin's cousin (second cousin?), and we talk a little. I see that she's a nerd, which isn't surprising, as my school is a mix of total nerds, jocks, and overly rich drama queens who have too much time to do stuff. Anyway, I hang out with my girlfriend and her second cousin, who wants us to all play games together and stuff with a group of her friends, whatever. So I go to join the group, and it's only the cousin. Which is wierd, because my gfs really close to her. Well, I come to find out that the cousin told my gf everyone was too busy and plans had changed.
So, we're hanging out, and the cousin goes totally silent. Not strange, considering there's like 4 other people in her house, and she's the oldest kid still living there, but she normally says "be right back" or something.
And then I get a text saying "Hey [REDACTED], I don't want to come between you and [REDACTED], so I'm not sure that I should tell you this" from her. I, being the curious little shit that I am, ask what she means.
I'm then told that she has a HUGE crush on me, and has since she met me, but didn't want to admit it to avoid teasing from other people, and to not make things awkward as all fuck.
Of course, she immediately says "gotta go bye!" over TS and leaves.
So basically, tl;dr version is my gf's second cousin has a crush on me, confusing the hell out of me, and now I'm kind of confused on what to do. Anyone been here before, and going to give me advice beyond "Dump your gf and leave the country" or something?
