I often help DH with school runs on his days with DSC.
I am currently off work on the final leg of my maternity leave and as baby groups have now reopened I want to make the most of these with a friend who is also on maternity.
Unfortunately the group lands on the morning I sometimes help out with school runs and it is at exactly the same time.
AIBU to say to DH that I can't do this anymore on this particular day unfortunately and he will need to make other arrangements between himself and ex?
