How should he move forward?

I'm a 30-year-old male. In 2017, I met a girl during my BTech internship period. We started talking, and after a while, she told me she had a boyfriend but couldn't feel the same way about him as she did for me. We talked through the nights until morning. I didn't force her into a relationship, but one night I told her I was in love with her. She said she felt the same but couldn't marry anyone because she had PCOD and couldn't have children. She didn't want to ruin anyone's life. I accepted this and suggested we could seek medical treatment, but she refused, saying she would live alone with her parents for the rest of her life. She even told my mom that I needed to marry someone else. My mom started searching for a girl and eventually, I was forcefully engaged. My hands trembled as I put on the ring. On my wedding night, the girl I loved called me, crying. Even after accepting my wife, I couldn't love her because the other girl never left my life. She would block and unblock me repeatedly, keeping me emotionally attached. Years passed, and she came back into my life again. Recently, she got a government job and told me her medical problems were resolved, and she had physical needs and wanted love. She called my wife and told her that I was emotionally weak and that I had talked to her for years. She claimed I said I could leave my wife for her and that I badmouthed my wife to her. My wife got angry, but I never said any of that. Now, the girl has finally blocked me everywhere. I don't understand why she did this to me. Please suggest what I should do.
