Dear Friend,
I don’t think she sees this relationship as you do. You say that you are in love with her. Love is a strong feeling. Love is something really big.
You are co-workers and see each other during work hours. Apart from the day at the train station you have not seen each other on a situation like a date or something like that. It seems to me that it is an unilateral thing. Therefore, there is no relationship.
Sorry, dear friend. Let me assure you that there are plenty of nice, good and well educated women available in India.
This one does not seem to be interested on you. You seem to be good, kind, caring and well educated yourself. Do not lose your time with this one. Join a volunteer group, yoga group, go for walks on parks, join a dating site, go to events, be proactive … You will find love when you least expect, until then enjoy yourself and your life.

Hmm…maybe she’s like me in this matter. I am not much of a phone/text person. Its not that big a deal. Its has just been 4 months. This anxiety is normal when you really like someone and dont see them often. More importantly, are you guys in a relationship or dating?
