My Boyfriend's First Love Cheated on Him

The day before my birthday, when I saw Zachary's message saying he had to go on a business trip tomorrow and couldn't celebrate with me, I felt only a moment of disappointment. But I wasn't surprised by his actions at all.

Zachary and I had been together for seven years, and we didn't spend every birthday together. In fact, he had only celebrated with me three times. Once when he first won me over, once when we were in the honeymoon phase, and the last time was after we reconciled from a fight.
