To be open or not to be.

Thank you for your advice, I totally understand guessing game is not fun and effective, but for me, in this situation, I am not able to do anything more

My logic is:

If a man is interested, he will take action, well, most probably, sooner or later. My radar is already up and can certainly catch signal if he is sending. The conversation last Friday, I was so nervous, not confident, I think I was worrying about my skinny jeans is not as fit as it should be, I forgot the belt in the morning.

If he is not interested, I can’t face that humiliation, even more at stakes when work is involved.

There is another slim possibility, he has not noticed me in a romantic way, this is the only room I can make an effort, i.e. get his attention and send some vague signal to test the water.
