Help. I'm feeling really upset and out of my depth here. DD1 who is 13, has begun being very secretive about texting. I agree with her that she should have some privacy, but felt concerned. Acouple of days ago she left her phone around with a message open. It was from someone she'd named "XXX" and I could see they'd said "love you too". I didn't read more at the time, but asked her about it. She told me it was just a girl from school, became a bit hysterical, and promised it wasn't a boy. Incidentally, I wouldn't mind if it was a boy, I just think she's too young to be mixing with/ contacting people who I don't know. Anyway today, she left her phone around again, and its clear that it is a boy, and one who she's never met. Obviously, this is very concerning. My ExH thinks that as DD1 is not so secretive as to completely hide her phone, then we should just monitor the situation from a distance without her knowing. Also, he thinks we should try ringing the number. Part of me agrees with him, I don't want to dive in an ruin any sort of trust we have, but then I don't want her to be in any danger. Am feeling sick at the thought of all this. Any thought wise MNer's?
