The original post starts by talking about teenage girls, then girls under 18. The next statement is about researchers speaking to young mums AND DADS aged 13 to 22.
It doesn't say whether those over 16 were married or not, but the fact that the 'dads' are included suggests that at least some of them had partners, whether or not they had married them.
Yet many of the susequent posts have assumed the girls had not stayed with their children's father(s). Does this tell us more about the girls' critics than about the girls themselves?
