Met someone on holiday

I was going on holiday in Spain with my family and i'm just a few days back. I met a Spanish guy who works as barman at the hotel. There were also other young guys working there and from the beginning they were keepimg an eye on me cuz a older barman asked me if i had a boyfriend just to tease me because the other guys were around. I observed the guy i like from the beginning and when i came at the bar he started talking to me and asking me personal questions just like an interview lol, also got free drinks from
Him. Actually the last 2 days we were getting to know eachother better and that night i decided to write my name and number on a paper and i gave it to him and he smiled but he didn't know what to say and i said to him; think about it and walked away, from the moment i walked away those guys started to talk very loud with eachother. The next day was my last day there but he didn't texted me yet on that moment but when i came there i saw him but he started to talk when i came at the bar and asked me if it was my last day here, he asked that already a few times and also asked me what i do school/work etc and he told me he works there until the 31th of october. The day i left i didn't expect to see him but he came looking for me because he knew the time i would left. He walked by and he gave me a handkiss and walked out of the door. Its 5 days i'm home now and 4 days ago i gave him my number. I really miss him so bad that i just want to go back there even if i could see him for a moment, is that insane to think that??
