my dd is in year 9.
she is staying at my sister's house for a week which is 2 and a half hours away without me and dh.
dd is very close with my 10 yo niece (her cousin) since she used to live with us since my niece turned 7.
at 11 o'clock they both got sent to bed at the same time. dd phoned me and dh for 10 minutes before she went to bed to talk about what she did, how she's feeling, etc...
dd spoke quietly with her cousin for about 3 minutes and my sister's boyfriend went in and shouted at her, even though she was allowed to talk until half past.
she was sent to another room and she's not allowed to go back in that room for her entire visit! she texted me to say that she misses home and didn't really want to be alone (she's only just turned 13, 2 days ago).
i told my sister before she came that she wouldn't really want to be separated from her cousin and she was feeling a bit worried about her boyfriend who can get a bit rough...
aibu to call my sisters boyfriend tomorrow to try to negotiate and explain the situation - really don't want a fallout.
