Can you hide your feelings from your face if you are in love with someone?

[TLK]

Hello,

if a person is in love with another person, and they communicate, can your eyes and face show that you are in love with the person you are talking to?

can your eyes or face show that? Can a woman see that a man is in love with her when the man is talking to her?

Looking forward to hear from you guys,

I just cant hide it. I do this all the times.
