<human>: So I just got out of a relationship a few months ago, and started dating this girl I reconnected with (we used to work together). We have a ton of fun together, and the first few times we hung out weren't "official" dates so I wasn't paying for everything. 

The last time we hung out though, she made a comment about how when she hangs out with her other guy friends it's "different" and I'm "treating her like a bro" since these friends usually pay for all her drinks and food and I didn't. 

I'm not in an amazing financial situation - I do ok, but with the breakup I'm paying for an entire place myself, plus all my bills, utilities, food, etc. - I can afford to take a girl out to a nice dinner like once a week and some affordable meals here and there, but I can't be dropping money left and right every time we see each other. 

She's mentioned in the past that she had a pretty well-off boyfriend who bought her a house, went on a few dates with a billionaire, and has told me her mom berates her for "having champagne taste on a beer budget". She spends a ton of money on clothes, handbags (she works in fashion), the kind of money I'd never spend on stuff like that. I assume she makes better money than me, because she lives with her parents but eats out every night, the clothes, etc. 

How do I politely get it across that I like spending time with her, but can't afford to pay her way all the time? Once in a while sure, but I'm getting the impression that she expects to be treated anytime we go out and do anything. It's not that I'm super cheap and don't want to spend money on women, but I'm trying to balance paying my bills as well as set some money aside for the future to buy a house (have a good chunk of retirement started and a savings account).

Can you give me the gist of the text in a nutshell?
<bot>: Just started dating a girl with expensive taste and different values on chivalry, how do I break it to her I can't be a sugar daddy?
