In any marriage, it’s important to consider your partner’s needs and wants, not just your own. But since many celebs are accustomed to being the center of attention and admiration, this doesn’t always work out. When two powerful people start asking one another to give up attention and time, resentment can brew. This problem can become especially pronounced when one celeb partner or the other is offered a life-changing job opportunity—one film, music, or book deal can completely change the direction of someone’s life. And when two people who aren’t willing to bend to anyone else’s will find that their lives are headed in different directions, that’s it for the relationship. This is especially true if a spouse becomes competitive, and subsequently resentful of their partner’s success. This was the primary reason behind the high-profile split of Scarlet Johansson and Ryan Renolds.
