W called you to ask for advice, you gave some, and she looked at it as you judging her. This reminded me of the caution about do not give advice even if they ask for it.
I think that is because we would tend to defend our given advice and escalate the argument. However, if advice is asked for, and you can remain calm and silent, I believe letting her vent some of that out of her is a good thing.
It is very nice to hear about your positive changes at work and at home. The kids speaking to you more - awesome!
btw I have a similar fantasy full of remorse and tears also. Yep, different path and much slower.
Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
