My eldest DS is 15, 16 at Christmas and has had same girlfriend since June - she is only just 15. chatting about summer holidays at weekend he asked if she could come with us. His assumption was that they could share a bedroom. DH had blue fit as she would still be under 16. A talk the following day revealed that DS regards whole deal as nothing to do with us and not interested in discussing it with us. Obviously that hurt a lot as we have always had full and frank discussions in the past. Anyway should I keep them apart when she visits / speak to her parents / or just resign myslf to the inevitable!!
