It Should Have Been Me by Jacqueline Francis

Catalina Diaz was my dream come true. Catalina Diaz was my future. Catalina Diaz promised me forever, and I was foolish enough to believe her. She lied. Forever, as it turns out, was just an infinite amount of happiness condensed into a very finite amount of time.

“I’ll be back in a year,” she told me before she boarded a plane, but that wasn’t true either. On the day she left, we didn’t realize that our paths were going to lead in two separate directions. The distance grew between us, and what we had slowly dissipated into something we couldn’t salvage. We both moved on, she found love again, and I accepted she was lost to me forever.

Well, I thought I accepted it…until I see her again.
Karma has always enjoyed messing with me, and this time is no exception. Her sister is getting married to my best friend and what better circumstance to run into my ex-fiancé again than at a wedding? Just one interaction and Catalina Diaz turns my whole life upside down. See, I still want her, but she’s happy with someone else. It’s painstakingly gruesome.
I keep telling myself that I just have to get through two weeks and then she’ll hop on a plane, and we can go our separate ways again. Just two weeks and then I can put all the memories of Catalina Diaz out of my mind for good. Easy, right? An infinite amount of torture condensed into a very finite amount of time. I’m sure I can do it.
