Good read. I think even those "ideals" play out different from couple to couple. Neither husband or wife are meant to be identical in what they can or can't do (obviously). Learning to honor the differences and show support is something that creates strong relationships.
I think a lot of times our instincts is to correct and mold each other into what we think is best but really for selfish reasons. When we learn to empower the other, it actually creates much greater potential for the relationship.
