I (27F) have a crush on my boss (47M)

I'm an associate (27F) at an accounting firm and have a crush on the managing director of my department (47M). I find myself attracted to him because he's handsome, funny, outgoing, mature, confident, and is successful. These are all the traits I want in a partner/future husband. I'm pretty sure he's still single but I will have to ask around. If he is, I don't know if I should make my feelings known due to the age gap. He might think it's weird because I'm so much younger than him and thus affecting our professional relationship.
