Inspired by another thread where people are talking about the secret to a happy marriage. And I see the usual compromise, respect, communication etc. But if one person cannot or will not give these kinds of things, then surely it doesn't matter how much respect you show the other or how much you compromise, or how well you communicate, you will never get that happy marriage?
I also see some people mention how the first marriage was terrible but the second is happy. And unless the poster has made some huge changes to who they are as a person (I assume this isn't the case), then it would appear the main factor contributing to their happiness the second time round must be the personality of their partner in comparison to the first person.
