Hey @irrahul! Thanks for sharing what you are experiencing. This is my advice. If you really like this lady you need to let her know. I believe that men should be brave enough to tell a lady what he feels and then respect her enough to let her make a decision. You make the offer. She is the one who accepts or declines.
I wish you the best. It is hard to be vulnerable, but it is good to be brave. You will never know unless you take the next step. But if she says "no" then you need to respect her answer.
