Adult dd ruby her grandmother to invite her for her birthday. He grandmother then said “just me” as her partner is has custody of her niece. Her nieces behaviour is very extreme which is why she hasn’t been allowed in my house. We have decided to let her in for a couple of hours however. Aibu to think she could come without her partner? She also started trying to play me off against my brother saying he had seen Christmas presents brought for me and my children and “had the right hump” I mean even if he did why did she feel the need to say it.
