Love / What do I need to know as an American about a Polish man? [15]

I have just began a relationship with a Polish man who is living in American now. He travels with his work to the UK frequently. He seems to be a Genuinely God fearing man and very affectionate. I have noticed some communication differences in our beleifs. I have attributed this to getting to know one another better. He has already indicated a long term relationship if not even marriage. He wants to give me the world! He seems too good compared to many american men. He is 51 and I have seen the stubborn already. I think it was more misunderstanding . If he feels I doubt him, he gets very quiet. I love this man; however, I have never had a man want to be so gracious! I am American born and bread and we both are divorcees. My children are older and he has one in boarding school because her mother passed during childbirth of their 2nd child. Neither lived. I live in the south and he lives in Fla. So travel is necessary. My income doesn't allow me to travel to him much; however, he says not to worry, he will take care of me.

I want to believe such a man exists and he seems so genuine......just kinda want to know what I'm getting into and the true expectations of a man raised Polish. His mother was Polish and his father American. I know customs are different and with his age it is refreashing to have the gentleman. I am 43 so there isn't much difference in our age.

Input please!
