DEAR HARRIETTE: I was dating this girl for about two years, and I always had difficulty trusting her, but I loved her. She worked in theater, so she was often on the road. I'd fly out to see her sometimes, but it ultimately just didn't work out. We broke up, and not even a year later, she got engaged publicly to one of her castmates. When they tell people how they met, it confirms that she was cheating on me the whole time. This makes me furious because I put so much into that relationship emotionally and financially. How do I move past this? – Mad at Her
