Comparing women never works, cause you'll always find someone more aesthetically pleasing or appealing and you'll never be satisfied. And looks can be overshadowed by the fact that your spouse makes you a genuinely happy person. If your spouse is highly attractive to you, then maybe you should start reminding yourself of it (''dang, I bagged me a dimepeice'').
All jokes aside, the stuff that your spouse does for you that is beneficial to your eeman will eventually overshadow their downfalls and what the other girl was lookin like will be a mere (clouded) memory.
I think you should always do stuff to keep that alive, like things that you know your spouse loves just to increase the love between the two inshaAllaah. So you can kind of slap yourself whenever these types of things come up.
(And if it's THAT BAD, maybe consider taking another wife.) :X
Yes, Allaah does know best because there are many brothers out there who are more than content with just one, so I don't think you can speak for all men when you say that akhee.
