really grossed out by my mother's actions

Jaimee

So my mum is just really annoying me as of late. .she posts really sexual things on Facebook and is always tagging her sister in laws baby daddy in them. it will be like naked women and posts about giving head and other various things....ive gotten to the point i have unfollowed her but she's started getting upset I'm not commenting on her normal stuff like I usually do because she doesn't know I don't see them. I told her I don't like that she does that and she tells me to grow up but it really makes me wonder if she's running around on my step dad...yes I know I'm a grown women but at the end of the day I don't want to see her making sex jokes with my creepy uncle. this guy has been making sexual jokes at me and my sister's since we were kids...even to go as far as trying to grope me as my 18th bday present thinking it was funny. would you be mad too?
