<human>: Condense the text into a few key points

First off, I've brought this up several times in the past (soonest being like a month ago), and she immediately gets defensive/deflects the conversation. "I don't feel like talking about money right now..." "I pay my half don't I? So why are you worrying about it...?"

These numbers are adjusted to protect my anonymous status... but they are fractionally accurate to her situation.

 - She makes $2,500-$3,000/month

 - Her half of the bills are about $700/month.

So, that leaves her around $2,000 a month in pure spending money...

She makes more then I do by about 50%. 

I have NO money problems. I buy new clothes, thinking about getting a new car, always fed, etc. 

She makes more then me, has the same bills... but IS ALWAYS BROKE. She's always picking up extra work shifts, being stingy with her money, and whatever else. 

I'm starting to get REALLY curious what is going on. 

 - Absolute worse case scenarios: When she says she's going to work she's actually cheating/doing something else... OR... She has a really bad addiction I don't know about... OR... she has huge amount of debt i don't know about...

I'm at a total loss. Like I tried to address is at fundamently basic as possible with her. "Look babe... you make $3,000, your bills are less then $1,000... where does the other $2,000 go?"

Never gotten a straight answer. 

Thinking about snooping around... or dropping by her work to see if her cars there... idk. Confronting her doesn't seem to work. Advice/help?
<bot>: GF makes good money, way more then her bills, but she's always broke/stressing bills. Does not make since. Not sure how to proceed.
