Love / How to propose to Polish women? [17]

Yes, asking the dad for approval certainly is respectable and shows manners, however her parents are divorced and she didn't introduce me to her dad (only her mom) even though we were in the same town (Elk) for almost a week. So, I guess I wouldn't propose in her home either (good advice though Jump Bunny) and probably will not ask her mom's permission. The idea of a hyphenated last name is a possibility as she will be a doctor and primary breadmaker in the family and might want to keep her name and sense of pride. What name would our kids take on? As for the engagement ring, I guess I should spare no expense, eh?
