I Am In Love With A Friend Of The Same Gender

So she told me she loved me ,but doesn't want to jeopardize our friendship,because "i am her rock." Honestly i can't help but feel as if she's lying to me. But when i text her about a girl its like her texting changes instead of "lol ok", she uses "...ok" and i realized she does it to every girl i seem to think is attractive. I'm really confused.
