Bar man greece

I went on holiday to Greece 3 years ago, I went with my family (mum&dad) when we were there we became very friendly with the bar man, my mum was up for a laugh so was he, and there was a lot of banter between us and him, it gave us something to look forward to when going back to the hotel. He took a shine to me and I took a shine to him. We became friends, I went to the bar and he gave me everything for free all the time! I never paid for a thing! He played pool with my dad and always had a laugh with us! When we went home I was gutted and cried all the way to the airport and after saying bye to him! I missed him so much I got a friend that I met there who was still there to give him my number, and until I returned the year after which was last year we kept intouch, we kept intouch without my family knowing though, we always called and text each other saying how much we missed being together. When we returned he was so excited to see us and had another amazing 2 weeks! He made me smile every single day and once again when we left I cried my eyes out and we kept intouch! He also cried when we went home last year. We went back again this year and once again he was excited to see us, he always give me cuddles and made me smile daily! He always still had a laugh with us and made our holiday the best for the 3rd year on the run! When we said bye I cried my eyes out AGAIN and so did he! We didn't want to be apart. Since we've been back all I've wanted to do is be back there with him! I love him to pieces he's amazing!! I know he has other people that go to the hotel as friends too and I understand I'm not the only one, also it's nothing sexual or anything as he's old enough to be my dad!!!!!! But I think the world of him. I always look at his pictures on Facebook and text him too! I look forward to phoning him and we always tell each other we love each other and miss each other, I think about him all the time, and when I see pictures of him with other people I get really really jealous, is this normal?????
