What more can I do?

Hey queens!

I have friend a good close friend of mine who has recently just broke up with her boyfriend of 9 years but mentally they’ve been broken up for about 4 years. He’s very controlling and verbally abusive. She finally gotten the strength to move out on her own but yet he stills try to control her. She tells me she’s done and she wants to take control back over her life but yet she still allows him to talk to her anyway and control certain things in her life.

I’ve listen, given a shoulder to cry on and given her my honest opinion and advise but yet she still choices to deal with the bs.

What more can I do as a friend without ending our friendship?
