Love / Just started dating Polish guy - what is typical of a man from Poland? Cultural differences. [78]

Hey there! I've just started dating a Polish guy from the past 2 weeks. He is super super super kind, gentle, romantic and have excellent manners. We are not intimate yet and he is not forcing it at all.

I am just a bit scared because we've dated 3 times and he is talking about marriage, serious relationship and assuming I am his girlfriend :)

We are both divorced having kids and he is 35. He offers to do the grocery for my house, take care of my daughter and myself and it sounds like crazy to me from somebody I met 2 weeks ago!!!

Is it just a typically Polish characteristic? Should I be worried? I don't honestly see or feel that he is a player.
We've very good communication and lots of things to talk. We're always laughing, joking and he's super funny!
Is this all normal? I'm sorry but I been thru so bad that sometimes is difficult to believe in good.
