<human>: I've known this girl for a few years, we dated in the past but it didn't work out due to me moving away.  Anyways I moved back closer to her and we decided to start up a long distance relationship a few months back.  The relationship is going fine, but last night she asked me a question about money that made me uncomfortable.

She was discussing buying this purse (160$) and asked if I think she should buy it.  We discussed it for a few minutes and then she asked if I would pay for half of it (80$).  I don't recall anyone really ever asking me to pay for something i'll never use in any way, and it was just pretty awkward.  I'm happy to pay for dinner, movies, presents around holidays, etc. but don't ever really just pay other people's things.

Summarize the given text in a few sentences.
<bot>: Gf asked for 80$ to help her buy a purse. I said no. Is it rude to ask someone else for money for a luxury item? Am i being stingy by denying this request?
