A friend of mine has a useful phrase to describe an experience I think many of us can relate to: she calls it “getting divorcey”. She isn’t actually married, but you don’t have to be, to recognise what she’s talking about.
Getting divorcey is what happens to her when her partner sneezes into his hand and then rubs it on his jeans, or when he chews his food very loudly, and when they disagree on how to raise their daughters and have arguments about money.
