Canvassing opinion and asking advice.
My friend's ex-partner keeps posting pictures of him with her son (aged 5) on FB. He's changed his main profile picture to one of him and her ds holding hands.
They were together about 18 months. He became abusive (cheated, controlling, lying) and she finished the relationship - he moved out of her house two months ago leaving her in a financial mess but glad he's gone.
He has pestered her constantly since.
She reported him to the police, who paid him a visit and warned him not to go near where she lives.
He took no notice.
She's blocked him from FB and doesn't return his texts. She can't see what pics he has up on FB, but I can and have told her.
She's spoken to the police again about the pictures and texts but the officer said that he's just sad and lovelorn. 
He is not related to her son in anyway and the relationship is totally over.
Is it ok that he should continually post photos of him and her son?
Should she do nothing and wait til he stops?
