I'm going to encourage someone I messed around with once to leave their abusive partner
Have you done this before?
She just need a push in the right direction.
It is good to help and get people out of abusive relationships. It might be good to get her some professional help and be a supportive friend as she goes through changes.
I'm going to her house with flowers, wine and a sympathetic ear and do what I can to get her to go separate ways from him.
That is really kind of you! I bet she will appreciate your love and support in that difficult time.
