Play it cool or make a move?

So I started talking to this girl 4 weeks ago. We both started texting each other and flirting through text. She texted me first too and she'd reply fast to my text msgs. She goes to a different school than me, and just had homecoming 2 weeks ago. She was still single and when I was texting her today I played it really cool, def not trying to be clingy. But my last text was " To lose in tennis" smirk iPhone emoji and her reply was "Oh.No. Well I'm on the phone with my boyfriend so I'll talk to ya later. Goodnight (:" I never replied after that. I feel dumb for not making moves quicker, but what should I do? I'm a good looking guy, fit, and surf. This guy plays water polo and is in the same grade as her, I'm a year older.

Well after reading your story, i had a bit smile on my face, if she said she is talking to her boyfriend
its very hard she will move to you, but as i can see you have courage to do this meet her instead of texting and try and talk to her.
