Does he like me should I keep flirting?

I think there’s something with this guy. I always say Hi or thanks acting more interactive and he says hi morning or hi. His voice always softer with me. He doesn't say as much to others. The other day getting off the bus. He didn't say anything to anyone else getting off only me he said you welcome smiling I had eye lashes done. Wore skirt caught him turning his head taking a second look at me as I walked on. As I was getting off the bus he wished me have a nice day first. Then another day gave him my number wished him have a good new years he gave wink as I was saying it , he saw I gave him a note asked what is this. He opened it , I got off he shouted have a nice day I said you too. He didn’t text me still acts nice flirting. The next time he saw I was was dressed up wished me to have a nice evening. Next time his supervisor was there as I got off he said you welcome winking replying to me. More months since I saw him getting off I said thanks have a nice day. He said have a nice day back. I went down a step turned back and said I didn’t see you in a long time. He kinda half smiles saying have a good day quickly maybe off guard he didn’t know what to say? Maybe shy?
