We stopped at my in-laws house to wish them a happy new year and while my SO was talking to his dad in the other room my MIL told me he got wasted last night and tried to rape her... I told her I was so sorry, and I really feel like that just wasn't enough; but it was all I could manage to choke out.. I didn't want to make a scene (she'd been speaking in hushed tones like she wanted this to stay between us), and they were walking back into the room almost immediately after she told me. I quickly shifted the conversation back to her needing to tell her therapist everything as soon as she can... Before we left she hugged me, and said I'm the only one who knows what happened... I tried to get out the door ahead of my SO, to get away before my FIL noticed I didn't say goodbye to him. I wasn't fast enough. I heard "she's not going to get away without a hug", and my heart sank right as I felt myself being pulled into the most stomach churning hug I think I've had in my life. 

My (61)FIL is a creep... But I really didn't want to believe that he was this much of one... And what can I do about it??? My (54)MIL is not stable, but will not leave him no matter how bad things get. She's always had her own mental health issues, but he exacerbates them with his constant mistreatment that can (clearly) get outright abusive. 

I'm typing this while my SO is in the other room... I don't want him to have to bear this burden... I wish I didn't have to either... I'm really not even in a good place with my own mental health, so how am I supposed to help anyone when I've never even been able to help myself?

Fuck...
