contrary to you guys,i have a polish wife that wants nothing to do with the almighty homeland
I think being a woman with a wife might have something to do with that. There are many great things about living in Poland but the treatment of same sex relationships is definitely not one of them (except for closet cases since most Poles have no gaydar whatsoever).
I'm sure that Poland will catch up eventually but at present the level of pubic debate on the issue is stupefyingly awful.
It might help to have a word or three with the wife ahead of time and remind her that even though you've been here before, you still have a lot to learn and she needs to let you know when you're going off course (in a non-hostile way). A code word might help that she could use to let you know to stop whatever it is you're doing and just sit there until she can explain what's happening.
Staying with the family is a mixed bag. You'll learn lots of practical Polish and having relatives stay for months on end is no big deal here but you might find yourself missing some privacy. If you don't have safe places to go in Warsaw to be by yourself you'll want to find some right away. It's liable to become an issue for you and one your wife is liable to not understand.
