<human>: Can you provide a brief overview of the text?

So my Girlfriend(F19) has quite the hostile relationship with her Mother, it doesn't affect our relationship much but it's painful to watch her so upset every time she goes home.

I always am there to listen to her venting whenever they have a fight and comfort her as best I can.

But as a Boyfriend (M20) I don't know whether or not to keep on trying to encourage her to have a talk with her mother or whether to allow her to just hate her Mother more and more. 

Because I can see it eventually going way way way south and her possibly cutting off contact with her Mother eventually.
<bot>: Girlfriend is estranged from Mother, do I try to get her to fix their relationship or just let her hate her Mother more and more.
