Daughter is 16, stays at her dad's once or twice a week. Until recently she had her own room at her dad's house but he has recently moved in with his partner. They have converted what was previously a dining room into a bedroom for her and made it nice for her. My issue is that when she's not there, her dad sleeps in her bedroom as his new partner can't stand his snoring. I guess it's fair enough that she shouldn't have exclusive use of a bedroom when she's only there for one or two nights a week, but she went there last night to find he'd left snotty tissues and dirty glasses all over the place and basically left her room in a mess. He's full of 'man flu' and has clearly been using her room to slob around in. He never changes the sheets after he sleeps in her bed and if this isn't disgusting enough in itself his personal hygiene is not great. AIBU in thinking that a 16 year old girl should have her space respected and her room kept the way she left it the last time she stayed? At this rate she's going to stop going to see him as she's so pissed off with him.
