Long distance relationship

I'm 21 years old and I stated to talk with my English teacher a couple of month ago, we started to talk casually but now everything is going so serious, he's 26 and he's living in Miami and I'm in other country, I'm afraid of falling in love with him because I don't know where this is going. He wants to live in my country and he says that he is in love with me, but I just to want to be disappointed. You guys think this could work?
