What's up everyone!

Two weeks from now it's my cousin's birthday pool party. Other then his parents and me, the rest are all friends. Amongst these friends there's his girlfriend's best friend.

I have a crush for her. We hung out twice because of my cousin, it was the first time I enjoyed teasing a girl, she made it feel natural. She's strong, she's got hobbies and she's pretty cute. All and all. I wonder what I should do.

I'm far from being a player, and I'll always prioritize fun over a girl (one of the reasons I don't get girls LOL), besides, my cousin is our only bridge. So I don't feel like risking burning this bridge just to try something stupid.

There's gonna be a bunch of people there, guys that she dated or dates to this day maybe.

So considering everything, should I try to engage in deep conversations, make her feel desired by expressing my desires or try to get a date, how would you act in my shoes?

Ps: The first time we hung out she was dating my cousin's friend, so I don't think her teasing was out of interest. I'm sure of it.
