DD is just 18 and has been spending a lot of time online. She doesn't have many friends at college (well, not any close ones) and doesn't ever really message anyone.
Since being online a lot, she is all of a sudden glued to her phone. Pulls it really close to her face if anyone is sitting near her to stop them from seeing. Speaks really quietly if she's on the phone in the bathroom or bedroom, etc.
I've asked "oh, who's that" and she often looks at me funny and says "a friend" but I know full well she doesn't have any irl. She seems very fixated on these online friends and I'm slightly worried about the risks. When I have heard the phone calls, they seem a bit flirty and it definitely makes me uncomfortable.
Would it be wrong to ask her when she's on the phone or whatever?
