I believe the person was simply reporting on the facts, and I think that pointing out that fact (that the new wife was young and pretty) was valid, as it illustrated one of the ways that the man's efforts paid off, how life rewarded his honesty, integrity, and commitment to do the right thing.

It made me feel good actually, some woman leaves him FOR DOING THE RIGHT THING . . . but then, eventually, why, he meets a great woman who is in many ways (including young and pretty) better than the other one. How wonderful! Good for him! Good for her!

I love it when someone who does the right thing is rewarded.

Would it have been better you think if he had remained single, or if he had ended up with a wife that was not as great as the one that left him?
