There’s (at least) one question in every important relationship, whether it’s your lover, your mother, your best mate or your favourite client, which can trigger the most almighty meltdown of communication. Something that seems to be taking a lifetime to resolve. Something that presses her buttons and presses yours just as hard. You know what it is. He knows what it is. You both know not to touch it, but every now and then one of you forgets and drifts into this dangerous territory.
Whatever it is you are unlikely to resolve it by talking it out just one more time. It represents something important that needs to be worked out through your experience of relating to each other, not through words. So, no matter how tempting it seems when they say “I know we’ve been over this, but could we just…” Smile, remind them (and yourself) that you love them and get on with being the solution not trying to explain it.
