I would appreciate some perspective here as I admit I can't really stand my ex so I tend to think the worst of him in most cases.
Kids stay with him a couple of nights a week. Ds17 sees friends on weekend evenings and this involves being in the park or someone's house until 12 - which is his curfew when with me. He then walks home. I used to pick him up but haven't for the last 18 months or so. Parties can be a bit later, but not many of these happen! We live in a small semi-rural town and all his male friends do the same as him, and some of the girls, though some girls do get picked up still from what I can see.
It has transpired that when he stays at ex's he has no curfew and ex is always asleep when he gets in. I think this is wrong. If something happened and he didn't get back ex wouldn't even realise until the morning, which makes me feel really anxious. Last night he was at ex's and I couldn't relax and was tracking his phone and ended up ringing him at 1am when it showed him still on the streets. He was with a biggish group (I could hear them) and said he would be walking home with a lad who lives on ex's street shortly, which he did. I now feel I can never relax when he is at ex's.
DS doesn't drink - never has and never wants to but I just feel uncomfortable knowing he could go missing/have an accident and it wouldn't be addressed for hours. Or AIBU?
