send her a message asking her where she trains.
arrive at her gym early. try to get a good view of the gym doors. pack for a long day bring a cooler of water and sandwiches.
when she arrives stay in your vehicle out of sight. when she leaves make sure you see which vehicle she gets into and follow her. try to put 2 or 3 cars between you and her on the freeway.
when you arrive at her home, drive past inconspicuously. later that night return to her home in your best suit with flowers and profess your undying love for her. if she pepper sprays you don't rub your eyes it only makes it worse.
hope this helps.
points for creativity, no one
Really, i don't recommend pursuing her.
Reasons:
-You added her because you think she's hot, but you're not connected to her whatsoever. -5 for creepiness
-She knows you think she's hot. So hot that you added a random woman on Facebook, a woman you are not connected to whatsoever. -1000 for her having the upper hand
But i suppose you have nothing to lose. I'd say you'd have a 10% success rate. What do you look like? You'd have to be disarmingly handsome for her to go out with a creepy dude who added her on FB.
