This person habitually attempts to deceive their wife, and from their own account describes her feeling antagonized. I don't think they are "forgetting avocados" so much as they are bullying their partner with plausibly deniable emotional abuse.
There is no abuse in this anecdote, either way. There's some passive-aggressiveness, and some dismissal, but neither quite rises to the level of abuse.
I do find the fact that people are accusing him of abusive behaviour here pretty scarey though.
