She was a wild child, she put her parents through it in her teenage years. And boom, here she is in her 30s going back at it. I'm not judging her mom, her sister seems very well balanced.
Edit// to add: her comment about loving Leah but not liking her is the most honest thing someone could tell Leah. She's all around so unlikable, even her mom can't stand her. She has no joy and no shine, she's just blah.
On RHUGT3: Everyone is glam, and Leah is looking like a washed out soccer mom.
+ Marysol is addressing her mother's surgery and her not having children. We learned more on 2 episodes than 5 seasons of RHOM.
