My marriage ended two months after our wedding

What happened? We got married last spring after six years together. Two months later she told me she had been seeing someone else for over a year, including during the wedding planning. She moved out the same week. What did it cost me? The obvious things — the flat, half our friends, a lot of money spent on a single day. But mostly it cost me my confidence in my own judgment. I kept replaying six years of moments, wondering which ones were real. Where am I now? Eight months on. I live in a smaller place with a cat I didn't plan on having. Some evenings are still bad. But I've stopped checking her social media, and last month I caught myself laughing at something without thinking of her right after. What would I tell someone going through the same thing? You didn't miss the signs because you were stupid. You missed them because you trusted someone, and trusting your partner is not a flaw. Don't let this teach you the wrong lesson.
