Well, to start, I'm not entirely sure how the cultural aspects of falling in love and maintaining a relationship before a marriage goes in India. However, I'll give you my advice according to how it's generally done in America (I hope it helps you a little).
First of all, if you feel this is the first time being in love, I have to say it...you're not. It's called infatuation, a "crush." There's nothing wrong with this, it's very normal, and if all goes well with the person of your affections, it can turn into love. But right now, what you feel is a desire to be with this young woman whom you've elevated to everything you want her to be in your mind, but you don't know her all that well as a person. You haven't said how long you've been aquainted with her, but to go from only "hi/hello" to feeling like you can't live without her and you'd change your personality for her in just two weeks is too fast to have genuinely fallen that deeply in love, especially since the speaking terms haven't progressed too much beyond "hi/hello."
Next, if I understand correctly, the extent of what you know about her as a person is that she is "kind of a broad minded person." That's good, but what else do you know that would be important to consider for a relationship? For instance, what are her religious beliefs? What are her political viewpoints? How is her relationship with her family? What kinds of friends and people does she associate with? What sort of interests does she have? What is her personality like when she's in a situation that's difficult to handle--how would she hold up?
These are all extremely important things to consider before getting deeply involved with someone or committing your life to them. She may seem wonderful now, but that's because you can imagine her as everything you want her to be since you don't know her all that well as herself yet.
Lastly, you sound like you have a very giving and kind-hearted spirit. This is good. Women appreciate this; to them, these types of personality traits are in the top priority of qualities and attractiveness they look for in a man with whom they want to share their life. However, this can easily turn into a negative thing for you if you're not careful, because you don't want to appear as if you have no assertiveness and you can be easily taken advantage of and manipulated.
You've gone into great detail of how you would change everything about yourself for this woman. Why? You have every right to be who you are and have no shame in your God-given personality. Some people are shy--they still can marry into a wonderful relationship. Some people are quick to conform and others are extremely stubborn--they still can marry into a wonderful relationship. Some people have disabilities--they can still marry into a wonderful relationship.
You should be careful of how willing you are to make yourself into anything she wants you to be. Changing some things about yourself is a good thing; it shows maturity and respect for yourself and others. But to be willing to change anything and everything is a really bad idea. If you want a healthy relationship with someone, you have to love and respect yourself enough to be the person you are, as you are, for them. And if they don't appreciate and respect you as you are as a person, they are not worth your time, because believe me, you'll never be good enough for them.
So my advice to you for pursuing this woman is this: try to extend your conversations with her a little at a time. Find out more about her, about who she is and what she's like rather than who you THINK she is. Ask her if she'd like to go to lunch with you or go get coffee before work one morning. Just talk to her and get to know her.
And lower your expectations of the potential of the relationship until you find out more about her. You really shouldn't feel like she is your reason to live just yet, because what if she really isn't interested in you--you'll be devastated, and no one should feel like life isn't worth living without a person whom they barely know. You're young and still have so much opportunity ahead in your life.
Right now your main focus with her should be just getting to know her because you're attracted to her. Let yourself fall in love if the circumstances allow AFTER you know her a little better.
Best wishes to you!
