Should I make a move on my coworker/friend

Okay so I (F24) have been crushing on this guy (M26) i work with for the past 6 months. He’s been in a relationship ever since we started working together so I never made any move and tried to forget about it, which didn’t succeed but at least we are now friends, but he just got dumped by her last week (they were together for about 8 months) So I am wondering when should I make a move on him and what kind of move should I do, am I supposed to be smooth or should I just be blunt and tell him that I don’t see him as a friend ?
