My step children stay 3 times a week, usually one night in the week and then over the weekend (although changes week by week).
This week there has been an exciting change at mums meaning we missed a night in the week as they wanted to stay there which is fine.
They are coming this evening and staying tonight and tomorrow night.
I go every Sunday to see my mum. DH wants me to cancel tomorrow because we've not seen the children all week and 'do I not want to spend any time with them'.
AIBU to say no? I wouldn't mind if we were actually planning to do anything but more often than not on a Sunday it will be a lazy day, we will stay in and watch TV and they will usually play with friends on their consoles / talk to them over headsets etc... So we don't actually 'spend time together' for the majority of the day, they usually have their headsets on sat in the other room.
I really don't think they care whether or not I'm there to be honest!
