MIL was a party girl had my wife at 17. Aalways put her self first i noticed this when we first met.
My wife always said she would be nothing like her mom. That being said some of the actions over the last 6 months concerning our marriage and how she has interacted with the kids she seems to have changed into her mother.
Not the party girl just selfish.
My wife and i talk i even get small windows to the old W. Just the extreme changes and the way she acts towards the kids
