Whatever works in their relationship I guess.

But it has struck me how odd the guy paying is when your just getting to know someone, I feel like paying creates debt as in you've now created an obligation to this person (in the anthropological sense I guess). Not really in a crude sense "ok you've bought me a latte, I guess I'll have to show you my bedroom ...". But in the sense of guaranteeing a relationship actually comes of it, but I can do no such thing when I'm just getting to know someone, but it does suck to decide after several dates "I don't think we're a match" and the guy has paid $100 or more by then. No not splitting the bill makes me very uncomfortable. Of course splitting it is odd, if your not sure it's going to be split and your in a situation where they guy has positioned himself in line in such a way that the body language and everything else is such that it says "I'm paying" and he doesn't and your just there in the odd quiet "uh, uh ... " blank stare at the cashier.
