can you help me

hey! me and my “friend” have been talking for a while like since last year. at first we were just friends I guessed I liked her but I never really tried because she dated a lot of boys so we became best friends. not to long ago like in septmber we started showing effections for on another (now she lives in another state). Now our feeling for one another is amazing we talk every day and even stay on the phone when were sleep just to tell each other good morning. we tell each other that we love each other but we dont go togather. well really the problem is she told me she still has feeling for her EX and still talk on the phone to him. that ticks me off but she says she no Obligated to me (I think I spelled that wrong) and that Bull to me. she just know told me and I dont want a part of that even thou she shows me so much love but yet it eats me up in side knowing that.
