Shattered Love by Nivia Borell

Bria du Mont and Damien du Sky have been in love for as long as they can remember. Neighbors and best friends since childhood, they planned to be together forever.
That is until Damien seeks to propose to Bria on her eighteenth birthday and finds her in bed with another man.
Bria has no memory of how she ended up in that situation, but Damien still leaves her. Traumatized by his departure, she develops broken heart syndrome and becomes emotionally numb in her search for closure.
Meanwhile, Damien drowns his pain in alcohol before becoming a ruthless CEO and a playboy who refuses to let himself love again.
Prisoners of their past, Bria and Damien prove incapable of staying away from each other. They dig deeper into the fateful night which tore them apart and uncover secrets which will threaten all they know and challenge the meaning and strength of true love.
