Have you ever thought “I wish my wife was more like [name of another woman]”? Of course what you mean is you wish she was more like another woman in one way, or a few ways. You don’t really want her to be like the other woman in EVERY way!
It’s not like we can pick and choose bits and pieces of women to make a perfect wife; women are a package deal. We get the good and the bad, the fun and the not so fun. What’s more, some of the things we don’t like so much come from the same place as things we like a great deal. The events that shaped her life result in a complex personality, and she could not just discard one part even if she wanted to do so.
The woman you want your wife to be like has her own problems, and her husband probably would like her to be more like your wife in some way(s). My suggestion is to learn to understand and live with the woman you have.
