You cannot apply British logic to Polish mentality otherwise you will send yourself crazy.
my God thank you for that - you are so right - that is what i have been doing wrong (and what has been driving me crazy!) ...
i also am involved in a complicated relationships where everyone has baggage and someone lied through their teeth quite a bit, so I can relate to the poster's predicament.
the thing he should remember is: Polish women very rarely, if ever, do anything that would jeopardise their financial/general security, and that of their children. They do, on the other hand, frequently do whatever is necessary to improve their position, in the quickest and most direct way to hand.
Po prostu, they do things differently to Brits, so if poster is a Brit, he should watch out ...
