I know an old couple who lived together for 58 years and still wake in the morning hold hands and go to Church, wearing the same clothes everyday and eating the same food everyday coz they can't afford any better. And still they're all over each other and they're still trying to get better. So long story short breaking up with her would be giving up and if you love her you won't give up ever, not even for what you think is for her sake. So do what you gotta do to be with her and Good Luck!
