Backstory - me and her dad separated 4years ago. During divorce lots of stuff came out about where all our savings had gone. There was prostitution use, he bought a house for one of his girlfriends, a car for another one. Since separating he has been with a few women that I'm aware of, one girlfriend was violent and stole money off him. He was investigated for supposedly sleeping with a 14 year old but the case was dropped for lack of evidence.
For a long time he wasn't interested in his kids and only saw them sporadically. My son is now in his twenties with a family of his own and has nothing to do with him, but my daughter is 19 with mental health issues and has recently been spending a lot of time at his house. It concerns me that suddenly he is inviting her over to stay, and I don't know what she does there because she isn't able to verbalise things very well. She is very vulnerable to trusting people who are friendly to her. I don't know what I'm frightened of, but I feel sick all the time she is with him.
She is with him at the moment. He was meant to be bringing her home today but she has messaged to say she is not coming back until Sunday.
I'm sorry, I don't know what I'm asking, I just needed to talk.
