I think I heard this from Rabbi Jacobson, a lecturer in theyeshiva.net but I don't recall where. In this lecture (minutes 39 to 47), he mentions it again:
That everybody has expectations in his wife before he marries her and after he marries her she is more realistic and this is learned from Yakov who married the beautiful Rachel and woke up to Leah
What is the source of this teaching?
If it is not accurate please correct it.
