I agree with AMN and Girlie, abuse is abuse.
However, not knowing the full situation I can't really say it is for attention. The abuser may be playing mind games with her. It is all too common. She will talk about the abuse but because of the verbal and emotional abuse she will not take action until she's had enough. Sometimes the fear of what the abuser will do is more than enough to keep someone in the relationship.
I learned some of this by being in a very verbally abusive relationship. Although I got out before the physical stuff happened (and it would have). Abusers play mind games that you are completely unaware of.
For now you can only listen. Offering advice will do no good until she is ready to accept it. Encourage her to seek counseling (my priest helped me see that and made recommendations). Also, pat yourself on the back for being there to listen and help. You are a good girl.
