“There is no difference in the objective compatibility between those couples who are unhappy and those who are happy.' Hudson found that couple who feel 'content and warmth in their relationship' don't believe having compatible personalities is the issue. On the contrary, they believe it was their attitude that made the relationship work. The strength of the relationship does not depend on how alike they are, more their willingness to adapt and build a bank of warmth and affection that helps buffer the annoyance of their differences. This supports the concept of the development of compatibility, having a growth mindset('I believe I can change') rather than a fixed mindset ('This is how I am'). Having an attitude of growth means going through difficulties and seeing them as an opportunity to know each other better and bolster the relationship through the resolution of the conflict.”
