Dating advice ?

So my cousin has this neighbor who comes over all the time. He's cool, he's funny, I met him a week and a half ago and have sort of grew a crush for him. The other day I was at work got bored and called my cousin, her, him and her bf were having a few drinks he asks her to tell me to come over. Well when I did he was at work my cousins sister asked me if I liked him because he really likes me. Well fast forward to that night we were all sitting in her dining room, he was just so interested in literally everything I had to say. Id catch him staring at me with these huge adoring eyes it just sucked me in. Her bf even mentioned that he liked me out loud and he didn't deny it. I found out from her bf what his number was texted him cutie and asked him if he really liked me but he's saying he isn't sure because he doesn't know me well enough but we get shy when were together plus with everyone else around makes it hard. Idk what to do. Help ? I'm 22 he's 23.
