In brief, this girl just joined our department recently, I saw her for the first time a couple of days ago, I am interested in her for marriage, I talked with her to get to know her, just general talk and she actually felt my interest.

The problem that I go to our department office once a week or twice due to my work nature in the field, so I decided to add her on Facebook, there were no mutual friends as she was new to the company, she didn't accept the friend request till now although it is so clear from my profile that this account is mine.

Reasons for not accepting my friend request is that she still doesn't know me well or she is not interest...etc whatever the reason.

My question is that I will see her tomorrow, sure I will not tell her or blame her about not accepting my friend request, but I want to know how should I appear to her tomorrow, should I express disappointment or act like nothing happened or what?

Many thanks.
