I don't know how much more i can do to help my mum?

I think yo should take her out somewhere and get her to enjoyherself a little...do something she liked to do like a movie dinner park..anything she wants and it would be the two of you with no yelling andjust enjoyable times.Tellher that you really love her and she dosent need anyone like that guy in her life...sorry but thats al i got..i went through this with my mom.
