Hello Mahesh,
You sound like a very kind and considerate person. I read your post carefully, and I think that you just need to give her a little time to figure things out. There is truth to the saying that “absence makes the heart grow fonder”. Sometimes when you are together all day and the evening too, it is hard to feel like you still have personal space. Some people don’t require as much as others, and maybe your beloved needs a little more time to herself than the living/working everyday was allowing her. She may have felt a little claustrophobic.

Try to give her some more time. If you can, continue to go on dates, keep it light and let the conversation flow naturally. Allow her to rebuild her confidence in the relationship and she may be the ones who starts the discussion with you.

I hope everything works out for you!
