2020 crush is going

So I've had a crush on this guy , and although it was obvious... well he never got the hint . I said this year would be the year I would tell him I liked him but this past Monday he put his 2 weeks notice at work because hes moving back to his country with his family , I've never talked to him outside of work , Today ! He told me it was his last day tomorrow Saturday, I don't work saturday so i saw him just today friday, not even a week has passed and he told me last minute, he said he was going to tell me it was next week but his plans changed, I pretended to be mad at him lmao but he knew I wasn't , i was laughing most the day because i didn't want to cry ... the day passed I saw him here and there .... at the end of the day I said goodbye (I hate goodbyes) I hugged him and told him I would miss him, he got serious for a bit then he said he would miss me too. I told him "he sucked for leaving and I hated him" , he said "learn to love what u hate" I could tell right then and there he liked me too but never told me. He gave me a bracelet for me to remember him and hugged me goodbye he wore the bracelet everyday , it fits big on me and I tried to fix it but it broke so I tied it together, although nothing ever happen between us more than just working together it hurt to say goodbye and I hope to see him one day and hope he comes back to the U.S. , I should of asked for his phone number or facebook or something but I didn't. Instead I was too afraid to even tell him I liked him and acted like he was just someone I knew.😔 And I still have time to ask , I know his sister but would that be ok? Would it do me good?
