The 27-year-old reality star tied the knot with Lamar Odom in 2009 after just 32 days of dating, and believes they have their unbreakable friendship to thank for their happiness.
She said: "When you`re married to the right person, it just works. It feels so good. Having the support emotionally and physically from someone that you trust unconditionally is priceless.
"I`m married to my best friend. We genuinely have fun together. You can`t force love, but when you let it find you, it`s phenomenal."
The socialite left her family in Los Angeles to move with Lamar after he was transferred to the Dallas Mavericks in December, and insists a willingness to compromise is essential for a healthy relationship.
She told OUT magazine: "I believe a happy marriage is about compatibility, honesty, communication, and dedication. We make sure to keep us - our marriage - a priority. We have to take shifts. When he`s in his NBA season I have to adjust to his life more and then when he has his off time he adapts to mine. It`s always a give-and-take.
"Keeping one another a priority and having genuine respect for each other is crucial. Without communication in a relationship, you`re at a stalemate, and that`s no way to live. We make our decisions together as a couple. It can never be a one-way thing. When you`re married you have to act as a team."
She continued: "My family comes first and foremost. My husband is my number one priority and he knows that."
