Whose Child Is My Wife Carrying?

My name was Jed Reed. I returned home after a business trip of more than two months and happened to see my wife at the gynecology department.

I found out that she had an ectopic pregnancy, had a rupture at 6 weeks, and had just undergone surgery a few days ago.

The nurse looked at me sympathetically.

"The time range from pregnancy to surgery is at most between 40 and 45 days, so there can't be any mistake."

I had never come home during my business trip, and my wife stopped working after marrying me. She didn't have any male friends either.

Who was she cheating with?
