Now and Forever by Megan Maxwell

Dropping a handsome billionaire CEO isn’t easy, but Jude Flores can’t forgive his betrayal. So she’s taking the steps she needs to move on—and far away—from her ex-boss, ex-lover, ex-whatever. And a good place to do it is at her father’s house in Spain.
Eric Zimmerman isn’t the kind of man who gives up. Nothing is going to keep him from following the fiery dream girl who’s left him a little brokenhearted and a lot frustrated. It turns out Jude is willing to play chase. But if he wants to catch her, it’s her rules or nothing. Not only does Eric agree to the demands, but their fantasies are hotter—and more forbidden—than ever before. Until the real world intrudes once again.
With the games on hold and reconciliation on the line, Jude must make a choice: trust in Eric and surrender, or start a new future without him.
