How do you know if a Scorpio man has affection 4 u

I am a Virgo girl. How can you tell if a Scorpion colleague is having a romantic affection for me instead of pure friendship? Help please!

If he makes an effort in particular to talk to YOU more and ask a lot of questions, or he just seems to be "coincidently" bumping into you just to spend more time with you...

I agree with gttommy, he probably is very friendly to all his colleagues- but if you notice that he is interacting with you more, then he probably is interested...

I have a question:

How do you know anybody has romantic affection for you, irrespective of sun sign?

I would guess..just trying to talk to you more.
