Multiple do-overs seeking girl.
That sounds like ... I don't remember. There was a story, with "Seven" either as the author or in the title I think, that just kept going and going. The guy would re-do, show up in the body of some character that was already present, (but with the MC's memories now) and accomplish a little bit, then get shot or hit by a truck, or something and pop up in some other body.
There have been a couple of genie's wish do-over stories that give a "do over" power, but the above story is the one I think of when I hear "multiple do-over".
I don't remember anything about Poland in that particular story, but I bailed out of it fairly early -- I just got bored.
The rest of your description does read like a mash-up of Richard Jackson and Stupid Boy, maybe with some Joe J's Pulaski saga mixed in.
