My friend has been in an emotional abusive relationship for the past 5 years. They recently had a massive argument and he left, at first she was determined that it was over, he got a shock as he was expecting her to beg forgiveness.
He has bombarded her with texts, FB messages etc. He made threats to kill, call social services etc. in the last week he has changed tactic and is being nice, saying he knows he shouldn't say these horrible thing, he's mentally ill, he can't help it bla bla.
She is now on the verge of getting back together, and I feel so helpless, I feel I should do something but I don't know what!
