Yes, Jerzy i will agree w/ u, he is not a GQ (Gentlemen's Quarterly) dresser. Often, i might see him in the same clothing he had on a few days ago, although they are neat and clean.
A few days ago ha ha ha. That is not bad.
I myself have two favourite comfortable checked shirts and I wear them in turns through fall and winter time. So in my case it`s weeks or even months ha ha ha.
I will try to probe to find out if i am an experiment for him and if so - this is unacceptable and i will address it. I refuse to be a trophy.
You should also try to find out if by any chance he has a family back in Poland. In Jaga`s article there is a mention about temporary affairs of Polish people who go to the USA, stay for a year or two, earn money and all this time live with an unlawful partner. Then they come back to Poland to their wives and husbands.
When in the US, I saw many relationships like that. Those people even went to church together. Unbelievable!
And in reference to the sex, he has not pressed the sex either. He does not appear to be assertive in that way. Although i wonder what is he waiting for b/c usually men try to get those panties rather quickly.
If he hasn`t pressed, it is quite a good sign. There is probably nothing wrong with him in physical context, nor mental.
He just treats you as a very righteous, decent woman to whom he cannot propose sex, at least not after a relatively short acquaintance. He probably thinks of you as a princess who deserves gentlemanly treatment. In his opinion proposing sex could hurt your feelings.
Is he religious? Even a little? Many Polish guys have this nice syndrome to treat women as Blessed Virgins. It is a result of Catholic religion and of a very high esteem in which Jesus` Mother is held in Poland.
