My Imaginary Ex (Used Paperback) - Mina V. Esguerra
Zack and Jasmine never dated, but no one else knows that. That story started in college, because she was being a good friend, and he needed help with something. The friendship and affection that followed were very real, but the lie kept causing trouble.
Years later, after a falling out and real relationships with other people, the lie resurfaces to bother Jasmine one more time--when Zack's exes ask her to stop him from marrying someone they think is totally wrong for him. She's the only one who can help him, they say, because she's his best friend. They also believe that Zack loved Jasmine the most--and maybe still does.
