How to Cope with the situation now?

Hello!
I met a girl in June-12 we got few university level courses together, we both were single in university, and both almost of same nature i.e shy, introvert..It happens like this that we become very good friends started to talk on sms/ calls on course matters and by time on social and other issues. by August, we wait for each other at main gate and then goes to classrooms together, sit together, laugh, lunch, study and all together. We both registered new semester courses together to make sure we are in same classes and that was by mutual willingness, i didn't forced her. It was all going fine.. Once in a class, i was sitting with her and my male friends of same class started to shout my name, and saying come sit with us...be with man's and etc...i went to them and asked them to be silence. or i won't talk to them..they stopped, when i came to her she said u better sit with your male friends they want you more, i some how make her feel comfortable by saying no matter what they want, what i want is matter...and like wise..At same night i received her text that i better ask my friends not to do this again other wise she'll complain coordinator. and if there's no such thing b/w us then its pointless to bear this kind of joke...that's the turning point i some how again approach her and make her realize comfortable and stayed away from my male friends for a while to make her feel good. it worked but then in public she started to ignore me, and almost make me feel that i am not their physically, she passes by some inches from me and didn't notices me, she just talk to me as a last resort, specially in the classes in which we don't have mutual friends. though i dislike this but i tolerate just for her sake, then after 2 weeks she introduces a boyfriend of her to me via sms and told me that she had an ex- BF who have came back, So naturally i made up my mind to forget her, then one day in university i asked her how's your BF? she replied no, not BF he's just my friend and nothing more..it seems that she's giving me another chance. Then all become normal as it was during Aug-Sep-12. Then again we registered for same courses for the upcoming session( Feb-13), this time i didn't even asked her for this bcoz by her actions i was not happy but she forced me to do so that come on why u taking such odd courses take these i am also enrolled, and i did.
Presently, this semester is officially ended. now Feb-13 will begin next month. She is not talking to me on any topic via sms and or call or in person in public anywhere from November-12, if i stop her in public she will stop and just answer my questions and nothing more, same on sms or call unless its very important she dont talk to me or simply yes or no reply, but when we are alone in the cafeteria or food court or in the corridor or waiting area where no one can see us at least mutual friends then she behaves as she have no other friend on earth, sharing and talking and everything, her domestic matters, etc, she seeks my advice on her very personal matters and etc....
I simply want to know...What's the issue? any one able to understand what's the matter? I never proposed her but via my text (poems, love msgs) and my extra care for her, trying to help her by going out of my way i reckon i have expressed too much of interest....
Precisely, Some time i feel that we are made for each other, and some time her actions made me feel the opposite. my friends now dont interupt or say anything but i just dont understand if she is just feeling ashamed of being with me?
Sorry for english mistakes. Please respond i just want to get rid of this matter now 5-6 months are toooo much...next semester she's with me too and in all 5 courses we dont have any mutual friends all seniors.

anyone any advice? Please read and respond i need help,

Hmm, some possibilities...
#1
If she is a normal woman she might have been unimpressed as to how easily you left your friends for her...you easily surrendered your relationship with your friends to be with her...you gave yourself too her way too quickly; having won everything right there, she has no relationship material left, no goals left, nothing to obtain, no future dynamic to the relationship. You might have to write her off as a learning experience, or maybe in time she might get interested again...just don't make the same mistake. Women today, especially young women, aren't like the ones of older times fell in love and got married before they were twenty. Today's ladies have many more choices, they want to play the field, which means they want to experience longer relationship dynamics. They don't want a guy to sacrifice too much right off the bat; it leaves them feeling smothered, and trapped into a confined relationship, when they still feel they have much to experience. So...get a lighter touch.

#2
Or she might have a problem...the most common male or female personality disordered trait today in western styled societies is narcissism. Maybe she was unimpressed by your friends, thinking that they were beneath her, and then by extension so are you beneath her. If this is the case, count your blessings and move on to someone far warmer and sweeter (and often, a better lover).

#3
Or she could be insecure and afraid of intimacy, due to some early trauma. She is avoiding you because she is afraid of getting hurt.

If she is #1, relax, don't obsess. Try and be casual friends, win her trust, start a dialogue, see what you can find out.
But if she refuses to talk, move on. Seeing her everyday won't make it easier, but it will be over soon enough if you focus on your course material. Only adolescents and crazily infatuated people want to spend every waking hour together; all healthy relationships need breathing room.

Let us know what happens.

Best,

Ignore her for a little while and she how she responds.

If the relationship ends, then it ends. Find another girl since nothing was going to come from this relationship anyway. If she suddenly becomes warmer to you, then maybe she's interested in you but you were doing something to repel her.

i think i gave her too much care...being there for her when she want or etc...may be she took me for granted..now i m trying to be casual and just friend with her first by keeping conversations point to point like she does, will wait for a week or two...to see if any change in her behavior..then will tell u!
