The Girl He Loves by Roya Carmen

Some secrets are meant to be discovered.
Mischa Lombardi is odd. Pragmatic. Perfectionist. Neurotic. Diagnosed with Obsessive Compulsive Disorder at the age of eleven, she can’t remember being any other way.
Thankfully, with the assistance of medication and therapy, her life is well under control. Some might even say it’s perfect: a beautiful husband, her sons Trevor and Tristan, a fabulous condo, work she enjoys and great friends.
Yet she’s still extremely fragile. It’s the reason she always guards her emotions very carefully. And unfortunately, nothing can help her when, by chance, she discovers her husband’s secret — Ava, a beautiful young woman. She was so sure she knew her husband, but now she desperately needs to uncover the truth.
It’s no surprise when she becomes obsessed with Ava, with every trivial detail of her life; her friends, her beautiful mother, and most of all, her gentle and sweet father. Driven not only by curiosity and obsession, but also by jealousy and lust, she heads down a turbulent path as she sets out to uncover everything about her husband’s secret life and all the mysterious people in it.
