We have ds and his boyfriend coming tomorrow for Christmas. We’ve met the boyfriend once over lunch, and he is lovely.
Dh wants them to sleep in separate rooms. Now obviously when they are in their own city they must share a bed as they stay over at each other’s places.
But when our dd had her then boyfriend stay for Christmas when she was 21, we made them sleep in separate beds then. Our parents agree as they were not married, but did say things seem very different today.
