Marriage is hard. It takes a lot of work and trust - from both people. Once that trust is broken it is so hard to repair.  This Reddit user tried to forgive while his wife continued to cover up her lies. But eventually, she was ratted Google.

"Fifteen years in, I found texts on her phone. I was completely blindsided. I had no clue she had it in her to cheat. She told me it was just texting and begged for forgiveness. I caved. A month later, checked the phone bill to find that it never stopped. I confronted her again - cue more begging and more denial on my part. I couldn't fathom that she would let the life we had built go down in flames. This went on for a few months. So many promises. One night, I caught her on the phone when she thought I had left.

She said it was just a friend she could talk to and she had let things go too far, promised to break all contact, swore it was never physical. Then I found emails. She detailed things that made me sick to read, but also included descriptions of his house. She broke finally but swore it was all just in the line of duty. That's how they'd met, you see. Visiting nurse service, and this guy was a client. Promised she was done. She loved me, you see? No chance she was going to let 15 years go like that. I wasn't buying it anymore, though.

She announced she was going out one night with a work friend. Promised they were only going to the bar, then she'd be home. Maybe late, but not too late. She had taken over her own phone account by then but wasn't bright enough to understand that Google Latitude still showed me where she was, and I wasn't about to show my hand. She kissed me goodbye, bee-lined right for his house, and was there until the wee hours of the morning.

Once I knew where she had headed, I called her dad and my best friend to keep me from doing anything dumb. I will love them both forever for keeping me calm while my world went freaking insane all around me. My father-in-law offered to stay with the kids and wait for her to get home. Around 3 am, while I was couch surfing at my buddy's place, she sent me a nasty text, asking where the heck I was. I texted her a screenshot of her little GPS dot at her boyfriend's and let her know I'd be sending her some paperwork soon."
