I find this very frustrating, as I’d say the majority of people don’t want an argument! Sometimes we’re not disagreeing exactly but having words & when he declares he doesn’t want an argument, it kind of makes it more difficult for me to state my case if you like. I remember my late DMIL saying that her DH was impossible to argue with. Wondering how best to deal with it. We had a bit of a fallout at bedtime but he did end up apologising for having a bit of a dig.
