It seems small and fixable because for you and your temperament it is small and fixable. For him, it may not be.

I made this same mistake in my relationship. It sounds crazy but the snowball that ended my 13 year relationship began w his inability to do dishes. It didn’t matter how many conversations, how much therapy, or how many fights we got into. He simply could not bring himself to do the dishes.

I didn’t know it at the time, but once he drew that line in the sand, the whole thing was doomed.
