With This Woman by Jodi Ellen Malpas

The Manor—the heartbeat of hedonism and pleasure, the place where Jesse Ward lost himself for years in women and alcohol, escaping his past—was his life. His everything. Until the day Ava O’Shea walked through the doors and Jesse discovered something else to live for.
Her.
Their love affair was passionate, intense, and all-consuming. She became his heaven. His escape. And eventually, his downfall. When Ava walked away from him, he was destroyed, even more broken than before.
But she’s come back, and Jesse vows never to lose her again.
Except Ava’s only scratched the surface of his broken soul, and as their relationship intensifies and their love deepens, Jesse’s pushed to the brink of insanity when his past creeps into his present and risks destroying everything.
They will never survive his truths, and Jesse will never survive losing Ava again.
So he’ll do anything to shield her from his dark, soul-destroying past.
Absolutely anything.
