usually girls have the tendency to fall immediately,,,especially if the man has the qualities girls are looking for...
but the decision is in you...surrender your feelings to God because He is concerned of you...He knows how you feel towards the man you are attracted to,,
confess it,, then renew your mind with the word of God,, remember that he is already a married man,, don't fall into the trap of satan to commit adultery,,,
Renew your mind.. because everything starts from the mind,, whatever we think,,we do,, then we suffer from it,,,
right thinking results to right action,, right action results to right feelings or emotion...
if you have a close friend who is concerned of you,, tell it,,,
and,,, treat him as a brother without malice......allow the Holy spirit to help you overcome it...
