Re: Need to vent
Is she bi-polar? Wide emotional mood swings aren't normal--as even your kids know. That wouldn't be an excuse, of course. There are other serious mental health issues she may have, if you read enough threads you'll see this with long term, serial cheaters.
But her mood swings could also just be a symptom of a 'normal' person compartmentalizing and living a secret double life. She was mysteriously angry or depressed and you couldn't see the cause, and she wasn't about to tell you. Hence the roller coaster for the rest of you.
