Gahh!! What am i gonna do? I need major help please..Long Storyy, sorry =(?

ok so this gurl named Jennifer and i used to be close friends during the end of 8th grade, the summer after 8th grade all the way through winter break. During winter break i told her that i like her more than friends and she told me that she liked me during the summer after 8th grade but she wasn't sure if she still does. At that time she was having major feelings for our friend Amy. She started to have feelings for Amy during the end of 8th grade around April and May. It all started when we all (Me, Jenny and Amy) were gonna hangout together one Saturday but i couldn't go anymore so it was just them to. So when they got there our friend Jessica was there to she she was talking about how guys mess with our heads and she might turn like joking around and Amy and Jenny laughed but then Jenny asked Amy "Hey maybe we should go out" and Amy said "Umm ok..?" So they were going out but they didn't act like it. So i guess Jenny broke up with Amy in September last year, idk but after that Jen started to have feelings for her. But since she couldn't do anything about it since Amy isn't Bi, she went out with about 2 people last year (both boys) but the relationship didn't last obviously. So later on in the school year last year she was telling me that she was basically in love with Amy and how she can't let go of her. So like i said, during winter break (the one that just ped) i told her that i like her more than friends and i would mention me liking her to her a lot and i didn't know it pissed her off and made her fell like sh*t until last summer (the summer that just ped). So after that we stopped talking. So now we go to the same school (last year we didn't) and we see each other when I'm going to gym and when I'm going to lunch. So we p each other, sometimes, like we don't know each other and I hate it. So last week Sunday, I believe, my buddy made me a Facebook (ya i know I'm late lol) and on Monday Jennifer wrote on my wall asking me to bring her a cookie or coffee because my step mom is the manager of a Starbucks in Miami, so sometimes I stay with her and she drops me off at school so I can make coffee sometimes. So on Tuesday last week I bought her coffee but we shared and after we drank it all she walked me to my cl and then she went to her's. So after that day, I texted her every other day that week and we texted and messed around and stuff and last Thursday she told me about when Amy agreed to give her a second chance (like going out) but yet again, they acted like they didn't go out at all. I mean if your gonna agree to go out with someone then at least try to make it work, but anyway so they acted like they didn't go out but Jenny was texting her like almost everyday like a couple but Amy was just like whatever. So later on when i i came to the school (like a week after school started) amy told me that she liked this guy named Pasta (hid real name is John but we call him Pasta) and how she wants to go out with him and stuff. So they end up kissing while Amy was "going out" with Jen and Pasta was going out with our friend Brittany. Then Amy breaks up Jennifer and finds out she kissed Pasta and she told me she cried. So Jennifer acts like that never happened to her and Amy because she doesn't wanna let go of her, like she feelings she has for Amy. But it pisses me off because she sees Amy in the hallway and hugs her and sometimes pokes her and runs to her cl but when she sees me she never does that. If i don't call her name or say "Hi Jennifer!" She won't say hi to me or hug me and I don't know why. So I tried texting her today and she didn't answer so i resended the message because sometimes it doesn't go through but she didn't text back and my friend Natasha thinks i'm in love with her and I'm starting to think so and she wants me to tell Jen but i can't because we barely talk to what's the point? We're just not gonna talk at all anymore and I miss the bond we had. it feels like she's straight with everyone else but when she sees me or maybe when she sees a text from me (if she gets it) she ignores me and acts like i don't exist. I can't take this anymore! I don't know what to do. i miss our close friendship we had and I want it back..And ya, I do wanna go out with her but idk what to do and since she likes Amy avlot, she doesn't like me for sure. So please help me. What can i do for us to be close friends again? Should i talk to her about how i feel? But we don't talk like we used to and it might make things between us more awkward and weird..Just please help me. I'm soo confused and sad and pissed off and i feel like everything Jennifer said about how she's gonna always be here for me whenever i need her and that she cares about me and loves me was a lie...
