i hope you being honest about your mental condition.

BUT if that is the case, then you have NO REASON to hit your wife since you are "perfectly normal" and able to think straight.
your reply literally admitted you hit your wife WHEN you are perfectly fine and under no mental issue condition.

you should be ashamed of yourself, you bloody piece of bullshxt.

ain't no one should trust a guy that hit a girl.
cuz once started, there will be 2nd , 3nd , 4th times and so on that particular person hit his wife again.
MEANING , a man that hit his wife physically is either 0 times , or more than once.

so you better make sure you response to your wife decision to stay with you.
DO NOT MAKE HER REGRET for giving you a chance.

yeah i know.
i try not to spell it out that blunt for this wife-beater since he claim his totally ok especially on the mental side,
but nvm , your sentence will do.

another possibility is he saw his wife is more success, and able to contribute more to the family than himself,
hence negative thoughts build up in himself (ego, self doubt, etc).

or his just a hot temper person.
