My husband, Derek, and I have shared our lives for what feels like forever. We’ve built a home, raised two kids, and intertwined our lives deeply. We even have a prenup, not out of distrust, but to avoid disputes if we ever part ways. I didn’t think I’d ever need it.

Derek has always balanced his role as a respected sales agent with his responsibilities at home, but recently, his frequent business trips piqued my concern. He left town almost every week, sometimes twice. Despite these trips, he never mentioned new clients or changes at work.

One weekend, while Derek was visiting a friend, I cleaned his car and found receipts for a hotel room in our town. The dates matched his supposed business trips. My initial instinct was to rationalize, but the seeds of doubt had been planted.

Determined to uncover the truth, I started paying closer attention and gathering evidence.
