In Gan Eden Adam and Chava were the happiest they could ever be when they got married. Why? Because they knew they were beshert, they knew they were destined for each other. There was noone else!!

Even though there are now lots of other people in the world, as soon as you are married to each other it's as if there is noone else in the world. Noone else that could be better, more this or more that, G-d chose your husband

 specifically for you and you only. Even if there is something you discover that doesn't seem to be perfect it's either because you can live with it or it's a test for you to work on and grow to be the person you need to !
