Love me or not?

I am too a love guru. but you know very well when circumstances come onto you that time could be something difficult to take decision for yourself. Now my query is My love love me so much but dont
know why she feel so guilty when she refused my perposal. Even that she is that forced to me that I
perpose her. But when time came she said i want to take sometime and then after 2 days she said no.
Cause i am a computer teacher and she is my student but between us there is only 3 years difference.
And when my fast friend propose her she said"yes"but in a commitment relation. i have no objection because with him she feels more charming and happiness.
1. So, tell me that am i doing something wrong or not?
2. If not, then why she did it so?
3. Now i have thought and decided that if she have love with me then she will have to perpose me and have to give me a huge. Otherwise no worry, i am cheerful to see her happy's mask.So, Have not I got
a IGO problem ?
