Yes, you're right--she is getting a good lesson in loving someone in spite of their bad behavior. A lot of other, less desirable lessons, tho, I'm afraid--such as how men should treat women.
And actually, I get the distinct impression that D chose not to tell me, not that she was told not to. I don't think they give a rat's patootie what I think, it just isn't a factor. She didn't want to hurt my feelings, and I overreacted (in D's opinion) to their first meeting so she wanted to avoid that response again.
