Long story short. Met a girl few days ago, had her laughing non-stop. We had a few drinks and eventually she leaned her body into my arms. I didn't take it any further as she was originally there with a buddy of mine and didn't want to start anything. Next day, I asked my buddy if it's cool and it was. I hit her up on Facebook and sent along the lines of "nice meeting you the other night, you seem like an ok human, let me get your number"

She sent a paragraph back and at the end she stated "you're gonna have to try harder than that to get my number ;)"

I planned on just saying "honestly, that's the hardest I'll try"

Any advice on how to go about this?
