If you leave - Courtney Cole

The second book in the Beautifully Broken series.
Ex-army soldier Gabriel Vincent is a badass hero. Or he used to be. Home from Afghanistan, Gabe can't stop thinking about that one horrible night on the battlefield, a night that changed his life for ever. He knows he's messed up, but with the help of a little beer and a lot more women, he's keeping it together. Until he meets Madison Hill.
Madison is happily single - or so she thinks. After the tragic death of her parents, she took on the responsibility of running the family restaurant, and that's all she has time to worry about. Until she meets Gabriel.
Though they don't know realise it at first, Gabe and Maddy will soon develop a weakness: each other. They need to be together to be whole, but can they find a way to heal the past . . . before they lose each other?
