I have recently heard, but not witnessed firsthand, that someone who was once a close friend is verbally and physically abusing her partner. My gut reaction is to cut her off entirely - I don't mess with abusers. I would love to call her out for her behavior, but we're not as close anymore and I've only heard this through a mutual friend, so I don't feel it's my place.
I guess my main question here is, if you have witnessed abuse firsthand, as our mutual friend has, what is the best course of action - ESPECIALLY if the abuser is someone you're close with? Do you call out their behavior, or does that put the abused person at too much risk? Do you cut off contact? Do you shift your focus to helping the abused? It's just hard to think that someone I once cared for so much is capable of something so awful. Support and advice welcome.
