Inappropriate In-Law
So I’m 24f, my sister is 35 and my FIL is 49. He’s never been a great dad to my SO, abusive to him when he was a child, walked out on them when my SO was about 13 and chose his new wife over his family. He’s made an effort with my SO over the last few years and has a much better relationship as an adult.
In September our only child was stillborn, and at the funeral, FIL met all of my family for the first time. Since then he’s been chatting with my sister. They both have mental health problems and she likes to ‘fix’ people. Apparently, he took this as she was interested, he’s been commenting on all of her Facebook posts, messaging her daily and making inappropriate comments to her. Things like how beautiful she looks and if they were together he’d spoil her. He’ll share memes that are a bit vulgar and tag my sister in them. He got drunk a couple of weeks ago and made a big Facebook post about her and messaged her telling her how he feels about her. She 100% do not feel the same way. She told him this a couple of times but he hasn’t relented. My SO hasn’t done anything or talked to him about it and I’m getting close to talking to him myself, I’m just concerned he’s going to pull everyone’s ganging up on my card and leave again.
