Her ex-fiance keeps saying, "We're just two different people."
When really, what he means is, "I'm so hurt and disillusioned that you don't want to spend the rest of your life with me."
Because the world is just two different people, ass!
Why can't you take two minutes out of your hurt to see what you're doing? You're destroying any chance you have of anything with her, and you're upsetting her while you're at it.
