hello, I am 17 and I know this girl for around 4 years now, we met in school and we have been kind of a distant friends ever since until around 5 months ago. We started talking over the internet, and even tho I have her cell phone we speak through messenger programs since she prefers it that way... I'm indifferent about which method of communication we use as long as we use any. Ever since we started talking she told me she had a boyfriend which at the time I did not care since we were friends anyways but it ended up being a lie so I was asking myself why she would tell me she has a friend when she doesn't and I guessed that she kind of liked me and I do like her. We kept talking for about 1 more month and she told me about this guy who she started going out with and this one seemed to be real... later she told me they broke up and she started talking to me about how she loved him and how she misses him ( i was surprised since they probably went out for around 2 weeks only), she started saying she was depressed and that she wanted to go back with him (he was the one who ended the relationship and I started to wonder why). Ever since I have been comforting her and she still haven't get over that 2 weeks-long relationship... she doesn't talk about it as often but still does... I honestly would like to go out with her some time but one of us has to have a problem and I am really confused about it. She barely talks to me and I have to start most of the conversations with her and when I actually start talking to her, her responses are ridiculously small, I have tried talking to her about everything and nothing seems to call on her interest... she is constantly saying that she is bored and no matter what I say she is still bored since she is not interested about anything (has been like that even before her 2 weeks boyfriend). I figured that it has to be me that she just does not like to talk to me so I have try to stop talking to her and after a little while she comes at me at school or writes me something saying that if I have forgotten about her and starts talking to me and when I think it is all going to be better I find myself back in square one. I have tried to talk to her about pretty much everything u can think of, sports, dancing, food, space, earth, nature, religion, hair, shopping, movies, internet, economics, math, video games, sexuality, art, relationships.... I just don't know whats left and I cant get her interested in anything. The only progress I have been able to make is making her stop saying "what ever" at least when she is around me. Another thing is that when I am at school I always try to talk to her and be close to her and there she talks a little more but about the same thing "I'm bored, I'm bored" she pretty much repeats it over and over again which makes me think I must be a really boring person. When I compliment her about her look or something (which she is not a model or anything like that, as a matter of fact there are many guys who would not even consider going out with her), she just laughs or says OK and never tells me anything back (I have never heard any compliment from her even though I have heard from her friends that she kind of likes me). Also, sometimes, actually most of the times she walks past me when I am standing some where at school, she pretends she did not see me and walks past me... I remember once I was sitting on the grass and she walks past me and I was pretty much the only thing standing there so I was 100% sure she had seemed me plus I stared straight at her eyes during the whole time and she did not looked at me once even tho she passed around 1 meter from me in the middle of no where, then when she was coming back, she did the same thing but this time a friend of mine who was now close to where I was called on her friend and I could see her trying to hurry so that her friend didn't come to where we were standing and when her friend finally did come she staid away, as if being near me when around a group of people was uncomfortable. That very same day I called her and talked about what had happened and she apologized and said she was sorry that she was an idiot and said it was not going to happen again (she now at least looks at me when she knows she just cant get away with "I didn't see you" but still walks by when there are many people around but I still know she sees me every time since I am pretty tall and unlike most guys I have pretty long hair which makes me hard to miss on a crowd).
This is got me really confused because now I do not know either it is her that is got the issue or she is extremely shy or I just have no clue of how to talk to a girl or she just doesn't like me at all and puts me aside until she doesn't have anybody else to talk to. Please, I would greatly appreciate any advice about what to do with her or what to stop doing or just anything you want to say, you can call me idiot if you feel you have to...
ps: she is 17 too, kind of skinny (must weight around 98 pounds) and probably 5-2 in height.
