Could do with some unbiased opinions here as in my opinion this relationship isn't healthy.
DS has just turned 17, he's in a relationship with a boy also 17, I'll call him J.
DS & J were best friends before they got into a relationship so I knew him quite well and he is a nice, respectful boy. They got into a relationship about 6/7 months ago and at first J would sleep here at weekends, or DS at his. Then slowly, it started being the odd midweek day etc, J then went on holiday with my ex and DS to visit family, this was for a week and after that they'd spend the whole week together and if they spent 1 night away from each other J would constantly tell DS he missed him etc. J then went on holiday and told DS he needed a break from their relationship to sort his MH out, so I thought this issue was fixed.
They've recently gotten back together and again it was weekends only, but this week has been every night, DS has stayed at his every night, except last when J stayed here. Tonight, he's staying at J’s again, so I messaged him and told him tomorrow night DS isn't allowed to sleep at J’s or J here, he's told me he can do what he wants and I don't care about J etc.
J did have a bad childhood and has told DS he has nightmares but he sleeps better and feels safer when DS is with him, obviously I do realise this is probably the cause so I'm wondering if I'm BU, or if this isn't a healthy relationship at their age and they need to spend time apart at night, WIBU?
