'D'H is currently living away from the family home (complicated reasons) with family about 2h drive away. We have an agreed schedule of him seeing DC weekly, but he also had an appointment in the town we live in tomorrow, and was going to also see the DC in addition to schedule. I asked him not to mention this to DC until there was a definite plan, but when DC asked him when they would be seeing him, he told them the day of the appointment. Earlier today he rang to tell me that his appointment is cancelled, so he now won't be seeing DC that day.
He thinks it's not his fault the appointment was cancelled, and doesn't matter as it was extra to the schedule and he will see them in a few days anyway.
I think he made a commitment to the DC when he told them he would be seeing them, and it's wrong to let them down just because they're no longer a convenient add on to his other plans.
