My gf gives her family most of her money?

[Rida]

Ok my gf I love her but we need to save for our future. BUt she gives 65% of the money she makes to her parents and brother for school. I think it is great to help them but this is beyond helping this is making it so she has NO future. We struggle some months but she still gives most of her money.
The thing is she never had parents she moved with her grandparents when she was young because her parents wanted a boy and could not afford 3 kids so they gave her up for her brother and now she must pay her parents forever because they are stupid??? she has not seen her parents in 4 years and her brother in 6. she told me if she does not sent most of her money her family might not talk to her!!!!! so they are using her as cash it seems. they did not want her and now need her for money.. what do I do or say??? she is 25 and has lived on her own for 7 years. we need our future to be bright I am sorry her parents made the mistake of having to many kids and did not love her as much as
