Straight girl crush?! Shes so confusing!?

Okay well ive known this girl for about a year now her names jasmin and ever since then we've become really close. Were always flirting and she knows im bi (btw were both girls, 17 & in high school). and she doesnt seem to mind we always hold hands, kiss each other on the cheek, gaze into each others eyes like were about to kiss , & we have like the longest hugs, weve taken gummy worms out each others mouths n our lips brush, bite each others neck and tell each other we love each other all the time! And one time in the locker room i leaned in slowly about to kiss her n she leaned in but then pulled away laffing nervously. Oh and one time when we were alone after school i stuck my tongue out at her and she touched my tongue wit hers! n it felt good! ((:and for some reason i get a certain vibe from her that she may be at least bi-curious. Or maybe thats just my wishfull thinking but anyways a straight gurl doesnt do that rite? everyone from our softball team always asks if were dating n she playfully says yea, and when i check other girls out or mention how much i miss this certain girl i used to date (even tho i dont) she gets mad & jealous! And gives me a dirty look, but then i mention how they dont compare to her and she gets happy.But the problem is she still says shes STRAIGHT ughh!! And it bothers me bcuz i feel like im just wasting my time but she has no idea how much i have it hard for her and love her!! And i want to tell her so bad about my feelings but i dont want to ruin our friendship and make things akward. Now the problem now is she's been going out with this guy named Johnny for about a month now. And ever since then ive bin distancing myself from her bcuz im trying to get over her, but its so hard bcuz she'll ask wats wrong with me n i respond saying nothing im fine. So now we dont talk anymore and theres this other girl that likes me named alejandra so ive been using her to get over jasmin but my feelings for her wont go away. So whenever i see alejandra during sb practice i flirt with her to make jasmin jealous, but idk if its working or im making it worse by pushing her away from me. So i guess wat im trying to ask is should i let her know about my feelings and see what happens or should i just move on to a girl that i no will actually go out wit me?. Thanks..
