DH has two siblings and they spent Christmas with his parents - we've not seen them since mid December. He's since found out that everyone in his family except for him has spent the weekend together twice this month (they don't live near each other). This happened quite a few times last year as well. It's very rare for DH to see any of them without the others, maybe once or twice a year.
I get that parents might want one on one time with their adult children, but it is so heavily skewed in the other siblings' favour I know this isn't about that just that.
DH is crushed by this, and his already low self-esteem is taking a battering. If his own family don't want to spend time with him, who does?
I'm conscious it might be an issue with me or with DCs, not him.
AIBU to ask one of them if there's a reason behind this? I suggested to DH he does this and he agrees but "never gets around" to it.
