Most of the people who post here are not Polish people who have moved to Poland.
Polish people who have moved to Britain you mean ?
I've been on here just over a year and I've got no idea who is Polish and who isn't really - apart from noimmigration, I think we all know what he is ;-)
I meet all your criteria but one - "enjoying living here".
Maybe it's too much to say I 'm unhappy living here, but at the same time it's far too much to say I enjoy it.
Anyway, good luck with your search.
I'd be interested in hearing your story. Do you see the bits you're not totally happy with changing any time soon ?
