Bro TS, please allow me to share my 2cent experience :

With some luck, time, money and patience spent, I had the chance to peek into TFC / FL / pretty local / foreign girl's phone before (of course in front of them), just a peek and I lost count how many guys msg and miscalls to her.
that open my eyes and from then I see them at most as "best friends" only.

in short, it is possible - who knows you're the lucky guy
But in reality you must be prepared for a battle royale with her lineup of other guys in her phone, the more attractive she is, the more guys she will be seeing.
