I'm not attention seeking, I genuinely need some advice because I don't know what to do or how to handle this situation, and I can't really ask anyone I know.... so anyone willing to boar themselves, read on...

I work with this guy, and his cousin came into work the other day and we exchanged a few glances, she exactly my type and I sure the way she looked at me she liked how I looked [on first impressions anyway]. Now, i've found her facebook through my co-workers facebook, but I obviously can't just add her as a friend because it'd look strange to my co-worker and I don't feel like I could just tell my co-worker i'd like to get to know his cousin more because it's his cousin... [does that make sense?]...

She came in the other day again and we briefly spoke in general and I've dropped hints to my co-worker but he just aint getting it. I have no idea what to do, I literally can't get this girl out of my head, which is strange because I've only spoken to her briefly, but when our eyes glanced at each other it felt right. This probably sounds so immature, but hey, I don't care, I just need some ideas...
