As far as simply dating, it wouldn't stop me if I liked her. Personal credit isn't really an "early-in-the-relationship" discussion topic for me. If things get serious and the credit is raggedy, you're probably going to have an inkling anyway, because it's probably going to worry her anyway, and you'll sense that. If it's jacked, then we have to talk. First, to see what her mind-set is about it (some, believe it or not are cool being heavily in debt.) If they're going to be "stiff-necked" (old grand-folks term of the day) about it, it's less likely you can do anything but be dragged down by them if you were to marry.
Finances, are a 2nd tier issue for me, but you gotta address it, because how could it not affect things? Over the long run, it's kinda hard to get your "swerve on" when you know Kaufmanns, Sears, American Express, et. al., are sitting on your dining room table waiting to kick your (rear) yet another month.
as was once said about our people's tendency toward over-consumption: just because it's on your azz doesn't make it an "asset."
