Should I be directly rude with him?

Yesterday I was working and suddenly the guy I like came with a male friend and a female friend. She was so much hotter than me. I felt like shit to be honest. I tried to give him my number but always on the last minute I changed my mind because he doesn't give any clear signs of interest (Except one day he came drunk/doped). Everytime I see him I try to get to know if he is interested but he only talks about himself. So after yesterday's punch in my self esteem and the lack of interest from him I've decided to put distance... But How can I do it without being rude?(I am always very bubbly and chatty with costumers)
Should I be directly rude with him?
