Based on a simple misunderstanding?
DH said this Saturday gone that he may be home for a conference call which was happening at lunchtime today. He doesn't get set lunch hours so left it that he would text me to confirm. We only have the one housekey as I lost the other so he needed me to be at home to let him in.
I didn't hear anything all morning so went to gym. When I finished my class, there were numerous texts on my phone saying that he was outside the front door and assumed I would be at home after what he had said. I told him I had heard nothing from him but he said 'You know I couldn't have let you know the day before as I don't know my exact lunch hours day to day so could only have let you know this morning.'
Got home and he's in a foul mood. Aibu to say he should have been clearer ?
