I asked DP to be a bit more thoughtful last night, and to pick up after himself. Basically he left a trail of stuff upstairs - soggy gym kit on the floor, bathmat in a heap, trainers dumped on the landing.
He responded by saying that I was just as untidy as him (which is absolutely untrue) and to "get off his case". I was very good natured up until that point and not agressive in anyway but he wound me up so much we ended up having an argument about it.
How can I handle it?
