His Greatest Regret by Belle Athens

"Stop embarrassing yourself, Cara. I love Chris."
"I'm pregnant, Chris. You're going to be a father soon."
On her wedding anniversary, Cara Smith discovers that her husband, Chris Knowles, has been cheating on her with her best friend, Jessica. Worse, Jessica is pregnant with his child, and everyone seems to have known except Cara.
For two years, Cara stood by Chris, endured his cruelty, and blamed herself for being unable to give him a child. Now he throws their marriage away for the woman carrying his baby.
Heartbroken, Cara files for divorce and walks away.
But Chris is determined to make her regret leaving him. When he threatens her career, he never expects the powerful CEO Romeo Armani to step in. Romeo is Cara's childhood best friend, the man she once rejected to marry Chris, and the one person who has never stopped loving her.
With Romeo by her side, Cara rebuilds her career and becomes stronger than ever.
A year later, Chris finally regrets losing her.
But it is too late.
Cara has moved on, and this time, she has found a man who will never make her question her worth.
