What actions should I take?

I have a lot of unresolved feelings regarding my relationship. There was a moment when she rushed to see her ex-crush while we were together, eagerly exclaiming, "Oh, you're so handsome," right in front of me and everyone else. I was incredibly embarrassed. This happened a year ago, yet it still weighs heavily on my heart. I tried to discuss it with her, but she dismissed it as nothing. Eventually, when she finally acknowledged it, she said, "I was just excited to see him." That hit me hard—it felt like a punch to my soul. To make things worse, she was upset with me for being upset about it. For context, she doesn't allow me to have female friends. I love her deeply and truly, and I can’t imagine walking away from her. How can I work through these unresolved issues, either with her or without her?
