<human>: This is a difficult question and it has a fair amount of backstory, but I really need help on it.

First of all, I am quite deeply in love with my girlfriend (Who we will call Elizabeth). She is devoted, funny, my best friend, incredibly smart, and literally speaking, the most attractive person I've ever seen. However, she is so kind, and so trusting, that her mother (Who we will call Leslie) has taken advantage of her, severly.

Elizabeth has stripped for money since the age of 18 to support Leslie. She also works retail jobs most weekends. Leslie does not work. In face, worse than this, Leslie is supremely self confident for someone who I would say is less intelligent than the average person one would meet on the street, leading her to use Elizabeths money to fund businesses that ALWAYS fail at huge costs.

This stresses Elizabeth out greatly, she works 18 hours a day on weekends while also studying at the university I just graduated from, she becomes sick easily now because of it, and is always very tired.

Elizabeth however seems to love her mother, despite her mother being extremely narcissistic and controlling. I've been unsuccessful in getting her to see what's happening to her.

Thankfully now, there is an opportunity for a change. She goes on her year abroad to Spain now. She officially retired from her club, and will not be working during this year abroad (The benefits of a high unemployment rate).

I want to know, should I stay or should I go? Is there any chance she will see that her mother is using her? Or is there no hope that I can have a happy life with this beautiful, intelligent girl.

Condense the text into a few key points
<bot>: My girlfriends mother uses her and massively disrupts her life, I worry that it wont work in the long run because of this
