Sabotaging My Walkout Queen

“How long do you have to convince yourself that you don’t love her anymore?”
David believed that he already found the love of his life at a very young age, but the girl broke their relationship and walked away without even telling him the reason why.
A second chance knocked as three years later, they met again, and David was really determined to continue what they left behind. They reconciled, but their love story gets tougher this time! They never talked about what happened and just let destiny tear them apart, making them completely devastated.
What really happened the second time? Would fate make a way for them to reunite again, or would David just continue to believe that he was intentionally hurt by the same woman twice, leaving him with no other option but to hate her for the succeeding days of his life?
