The Ruin I Chose (Devotion & Damage #1) by Velrith Rose:
 
Sometimes the person who heals you… is the one you hurt the most.

Interior designer Roxanne Talati isn’t looking for love when she travels to Italy—only space to breathe after years in a suffocating marriage. But distance brings clarity… and Marcello Vitale, a man who is everything her husband wasn’t—controlled, intense, impossible to read—begins to unravel her carefully held world.

When secrets come to light, he walks away.

Months later, fate draws them back into each other’s orbit—into a world of restrained passion, sharp edges, and a love that comes with a price. The man she thought she’d lost forever returns—changed, watchful, and far more dangerous to her heart than before.

Desire and guilt collide in this dark, addictive romance about second chances, forbidden longing, and a love that both heals and consumes.

A love that ruins before it redeems.
