what should i do with him?

long story short: i do like a boy, like a lot, you can’t even imagine how much. he’s just perfect for me, all what i want to see in guy - he has. he’s smart, he’s funny, he’s going to gym, working and he’s unbelievable handsome. we are from the same city and the same gym, but year ago he moved to Poland and now we’re just chatting ( we started saying hi to each other and started following each other on ig about a week before he moved to Poland). the problem is: he’s gonna come to my city next month and he would like to meet me. how do you think should I tell him that I like him? If I told him, what’s next then? he’s not gonna stay in my city, he’s gonna return back to Poland and long distance relationships are just wild and absolutely not for me
