We have DSC 50:50, 4 nights one week, 3 the next although it always ends up being more one way or the other. I can't remember the last time we actually had them 3 nights in a week, it is always either 4 or 5 typically.
Basically whenever we seem to have any free time, DH is always asking if the kids can come round, can they come for tea, can they stay and extra night etc...
AIBU to wish that just sometimes we could actually have time together when they were supposed to be with their Mum? She always bites his hand off at any request so it's always agreed.
For example, this week they were with us Mon-Fri, picked up by mum on Friday from school. And he's already asked if he can have them tonight too. I never get a say or asked. He apparently doesn't like them not being here on a weekend, feels wrong etc...
I don't kick up a fuss, I never make the kids feel unwelcome but just sometimes I wish we could actually stick to the arrangement so I know when and where they are going to be.
