Love / Getting to know a Polish Man who's first time he'e ever been in the USA [12]

Hi all,

I don't speak any Polish but have found an interest in an individual who has recently moved to the USA. He is very wrapped around his work and showed some interest before. I asked him out and I am thinking this may have been the wrong thing to do. Is it not acceptable for a woman to approach a Pole and ask him out in Polish culture? We did have a very nice time but I am not sure if I should ask again. I think he may be a bit overwhelmed by the American culture. I just want to be friends right now...I don't expect anything. I'm relatively new to the area and haven't made many friends, he seems very interesting and I'd like to just get to know him a little more but again, I'm a bit nervous to just ask if he'd like to grab coffee. I see him regularly around work and he is very professional, I keep it that way as well but I sense a little interest and I'm not sure if he is just shy or if it just takes a really long time to get to know people from the Polish perspective. When no one is around we talk and he smiles the entire time...is this normal behavior to smile all the time when talking to someone or is it an indication that maybe he likes me but is just shy? Keep in mind, he is an older man, in his 40's, quite handsome and grew up during the fall of communism so he is not a typical man, not anything like the men you'd find in the States. He is very reserved and very work oriented, doesn't have much of a social life either. Would it be appropriate to just ask for coffee/tea or should I leave it alone?
