DD finished year 11 a few months ago, and she'll be 16 in a few weeks.
On Sunday, DS told me that DD has a boyfriend and he's 20 (DS found out from one of his friends at school as her boyfriends younger brother is in his year). I spoke to DD about it and she kept denying it. Yesterday, she admitted that she does and he's her friends older brother. I have never met him, but I do know DDs friend and have met her. DD goes around hers a lot.
I really don't know what to think! I haven't said anything bad about him but I feel uncomfortable about their relationship. Am I overreating? Is there anything I can do?
