DS is almost 20 and in his 2nd year of uni. He struggled during the first year but managed to get through it. This year, he's been struggling but agreed to stay and I went to visit him a few times. A few days ago was the anniversary of his dads death (12 years ago, not recently but obviously it's still affected him) which seems to have hit him hard as expected. He called me last night crying saying he wants to come home so I agreed at the weekend ill go and get him.
The issue is his room, he sleeps in it when he's here but when away SD(12) sleeps in it as she doesn't want to share with her sister (7), they come here every other week and stay for the week. The issue is they're also coming this Sunday. DP has said I'm BU for wanting them to share and DS is almost 20 so if he can't cope in uni he should find somewhere else to stay, for example a hotel. I've told him I don't expect him to do that as this is his home we then argued about how this is also SD’s home etc.
Was I bu?
