Been seeing each other about a month, read a comment on FB which leads me to think she has lied about being at her mates for a sleepover after a party, when she may (highly likely as she came home with big hickey) have been at BF's. A pattern emerging of never coming home when she says she will, always "nearly home" or "now I'm at Dardedars house". She's not on the pill. I am worried about her only being 15. I want her safe.
