Thanks DS! Those are some harsh words you had thrown at you, much worse than what my H said to me. WAS can be so vicious and angry, I feel like saying "you are getting what you wanted, why aren't you happy about it?!"
With regards to self-correcting, another 'save your relationship' program (female-oriented) suggests to recognise and apologise for any disrespectful and/or controlling behaviours. In this case, it was a case of 'reply in haste, repent at leisure' for I felt badly about my terse response. My conscience did feel lighter once I apologised, so I feel it was the right thing to do. Next time, I'll take my time replying to prevent emotional responses.
Re. GAL - it's very hot! Very sad about all the fires burning up the country.
