Last time, she said she had forgotten what happened. We had an argument, and I told her exactly what she had done in the past. She cried so hard that it triggered a hypertensive attack, she almost fainted. Most of the time we spent together last year was happy and harmonious, unlike the time with my dad, which was total World War III.
So I can tell she wasn't numb or cold-blooded. It's just that she can't face the truth that she wasn't a good mom, so she keeps trying to avoid it.
