Do you think i have a chance with her? btw sorry its long?

Ok so i like this girl named Jennifer. Ive liked her since the summer of '09 and told her that i liked her more than a friend during winter break last year but she said she didn't know if she liked me like that. So Jennifer likes our friend Amy and during summer of '09 Jennifer asked Amy out and Amy said yes but Amy doesn't like Jennifer like that and they didn't even act like a couple. 4 months later they "break up" and start dating either people. Jennifer likes Amy a lot, basically in love with her but even though she dated other people she still was in love with Amy. So during spring break '10, Amy promised Jennifer she would give her a 2nd chance whenever she was single. So the beginning of this school year they started going out again but kept it on the down low like they did they first time the went out and they didn't even act like they went out. Then Amy starts to like this guy John and she showed me the text messages they would send each other and i told her he liked her to, but while they were flirting with each other, Amy was "going out" with Jennifer and John was going out with this girl Brittany. So later on, Amy and John kiss/make out and Brittany finds out and breaks up with John and Amy breaks up with Jennifer to be with John and Jennifer told me she cried a lot =/. So a little after a month Amy and john are going out John tells Amy he still loves Brittany and Amy breaks up with him. Then a few days later she tells Jennifer that she will give her a "real chance" like she said she would which is b.s. because she promised Jennifer she would give her a second chance and never tried to be in a real relationship with Jennifer. So Jennifer was thinking of giving Amy a chance even if it was a risk. So like 3 days later, John asks Amy out and they start going out again and when i found out i thought about Jennifer and i wondered how she would feel when she found out. She later told our friend Natasha that she was done with Amy. She also told Natasha that she's still basically still in love with Amy, she doesn't want Amy out of her life, she doesn't want to ruin their friendship, etc. and Natasha told her that Amy lied to her and broke her heart and Jennifer knows that and she said she also knows that Amy isn't bi or a and she doesn't know what to do. Then Natasha asked her about me and Jennifer said that she hasn't talked to me much and she hasn't talked to me about the Amy thing because she doesn't want to use me which i thought was thoughtful and adorable. But she basically told Natasha that she would get mad if this guy named Cesar goes out with this girl she has a crush on named Jackie so she basically wants to use Jackie as a rebound so that means she cares about me and not Jackie...rite? Grrrr! Im confused and sorry its long and confusing but PLEASE HELP ME =/ an IM SORRY lol
