I have found no one here who remotely considers her a saint
You're right we have only known her as a girlfriend for ten months. But we're not judging her on her abilities as a girlfriend. We are judging her as a human being, which she has been far longer. If they wed, she will still be a human being, not a stepford robot. So it's important to also judge a girlfriend as a human being.
Fortunately as Meghan is not some unknown, we do have things to go by. We know more about her then Cressida, Chelsy and Kate this early on. Because all we knew of them was as a girlfriend and odd rumor.
She may have been a girlfriend for ten months, but she has been a human being for thirty five years. And she seems, though not saintly, a pretty good one. She has an education, a career,
does charity work. These are all traits any parent would be happy to find in a perspective daughter in law.
Just as we don't think she us a saint. We don't think she needs to have cured cancer, have a Phd and look like a super model as some posters do.
Meghan as a girlfriend we need to see more. As a human being she has done pretty well so far. And that's half the job.
