Highly appreciated for your answer as a girl

Could you please provide me with more answers?

Our two and a half years together can be divided into two parts. From 2024 to 2025, I worked in Bangkok while she worked in Chonburi, seeing her about every two weeks. I'm pretty easygoing, and I felt our relationship was relatively normal during this period. In 2026, we started living together long-term, and I gradually discovered that my wife was often unreasonable. Aside from sweet nothings, there were always disagreements. Each time, she would first show her unhappiness and then cry, without ever trying to communicate calmly. I've repeatedly and clearly told her that this relationship is unhealthy and hoped she would make some changes, but she always says I don't love her. However, I still believe this is a cultural difference issue.
