How to approach from Greece online?

[Sw33T]

Hi! So last summer I went on vacation in Europe and while I was in Greece for a week I met a guy on the beach. We went out with his friends one of my nights there and they were all nice and fun to hang out with. Then I left and came back to the US where I live and while having this greek guy as a friend on Facebook, I notice one of his guy friends and decide to check out his profile. I instantly fell in love not with the way he looks and after creeping his profile enough ) I also noticed we have same taste in music and other things. I decide to message him and say this "Hi! How are you?Can you write english? Lol", he responds something like "Hey I am fine, and you? I dont know very good english" then I decide to go all for it and say it to see what reaction I get from him. So I say "I see.. Anyway i wish we would have met when i was in Greece this summer lol" , the he says "I hope next year you will come again and then we can meet!!!!!" and i finally respond with "I wanna come next summer but i'm not sure if i will make it. I hope i can tho" to which he doesn't say anything back anymore. Obviously it is weird enough that I tell him that so what can he say back, we don't even know each other.
I am a pretty blonde european girl so I'm sure he would like me but I can't know if we would be compatible other than for the looks. I got a job recently and am planning to go there in the summer for a month or so to see if something happens, even if nothing happens between us I would still go and have fun. I am thinking to message him again and try to make conversation but I really don't know what to say as he already told me his english is not good. We are both 23 and I think he is single as well. I know greek guys are into lots of girls since there is so many tourists there all the time, but I would like to see if something can work out between us. I would ask the guy that I met there to see what he says about it but that guy is somewhat interested in me, at least he was when I was there , although nothing happened with us, so I think it would be awkward. Any advice to how can I get us to talk so I can at least have some assurance that there may be a chance for us to meet if I go there? Thank you!!
