Hi so just for context we have a 2 year old that has no contact with my partners dad or his enabling wife she to him being accused of being inappropriate with a child (SIL friend) although he wasn't convicted his wife doesn't believe that he didn't do it! He was also watching a woman with binoculars, taking photos of women in Tesco and hiding in the bathroom afterwards( my sis in law was with him),he's also been inappropriate with me trying to undo my bra and also groping his friends daughter, his wife also has bells on her bedroom door because he tries to be inappropriate with her and the son has a lock and found incest porn on his phone. I'm just a little taken aback that my sister in law is willingly bringing her child into that situation should I have a conversation with her? I'm struggling because it honestly makes me sick.
