Sorry I know the title is vague, I really didn't know what else to put.
I have a good friend who is in her early 50's and is lovely and quiet by nature. Her daughter is married to a man from another country, he has been part of their family for about 5 years and they got married last year. Since the wedding his behaviour towards my friend (his mother in law) has changed, at first just making comments she thought were strange but maybe also thought she was misunderstanding because English is not his first language.
7 months ago during a family party at the end of the night after a lot of drink he grabbed her inappropriately and pinned her by her wrists against a wall when they were alone. She said and did nothing about this and put it down to drunkenness and it was never spoke of between them after however he continued with the "off" remarks.
Two days ago completely sober they ended up alone in her house by chance after a family dinner and he cornered her in the kitchen and tried to kiss her. She fought him off and told him he was completely out of his mind and he gave her a whole speech about how he finds her so attractive!
My friend is terrified to speak out as she's worried about many possibilities, her daughter's life being ruined after only being married last year, not being believed and losing her daughter if she picks her husband's side. Her own husband going mad and attacking the son in law if she speaks out and getting in trouble himself for assault etc.
I'm truly worried that if she does nothing it could progress to him actually hurting her or raping her to be honest. How can I convince her to speak out, or is that even the right thing to do as a friend, should I just listen and not offer advice? I'd never forgive myself if she was hurt by him and I'd not helped knowing the back story.
