Lesbian issues(is she interested or not)

Ok the story is long but I'll tell u any ways.

So I noticed this girl thought she was gay, but she didn't seem very friendly.
So I thought FUCK her, fast foward a year later. I'm going through a tough time wiv ma mom broke up wiv ma chick.
I'm revising for an exam after coming from the hospital to see my friend, the library is packed so I sit in the cafe'.
Fast ward... I'm on ma fone something tells me 2 look up (I'm looking like shit by the way very shit like tramp like) cos I was broken hearted n stressed!

I looked up n this chick is staring @ me so I was like huh! I sit up start reading my book she comes by the second time still staring. I look at her n she quickly looks away again, so I'm like freak!
A week later she starts staring again so I stare back thinking she'll stop. But no this carries on for nearly 3months. So in august I see her she stares again so I get missed.
I then go 2 check out a book n she stares again wiv out speaking (she was a librarian) fast forward september I wrote her a note. Telling her I liked her(which I did) but purely just 2 freak her out.

October the 19th my friend tells her that I sent her the note, and that I liked her. So november I go 2 da library wiv ma friend lisa, who is hot ( so this chick walks, to the other side of the library to stare @ us as we were leaving).
January she sees me in da library on the phone talking, tries 2 stare again but I turn my back to her.

Ten minutes later she writes me a note( saying thanks 4 flattering her n that she was leaving her job) errr why did she have 2 tell me. (Bearing in mind that she's in a relationship) ok so I write some bull bout how sad it is that she's leaving blah.
As soon as she sees me she has this big smile on her face. Fast forward a week later. Its her last day so she's gon have drinks wiv her friends, I'm going out 2 dinner with my friends.
* out of politeness I ask if she wants 2 join us* " she says yes but she has plans 2 av drinks*, but her friends don't turn up she'll come.

As I'm leaving she calls me back like, wait how I'm I suppose 2 join u if I don't av ur contact details. So she hands me her fone n I type my number in.
"Bitch didn't even bother 2 tell me that she couldn't make it" * a week later I find her on facebook (so I send her a message, not adding her 2 my friends list) she adds me so I accept her.
So we talk 4 a while emails n chattin

online, I then sent her a message a month ago *asking her specifically that of she had not been in a relationship would I have stood a chance?) She ignores my email 4 like 3 weeks. So I send another saying oh I'm sorry if I put u on da spot lol. She ignores that 2. I tried 2 chat 2 her online, she ignores that.
But writes on myfb profile when it suits her.

I mean I like her soo much that my heart skips a beat when I even see her name.
This situation isn't normal is it? Btw we are both lesbians.

Myfriend sent me this email and I need help responding.
