Pink reflects on what keeps her marriage together and the importance of therapy

"It is our relentless and stubborn idealism that keeps us together."

Having been married to Carey Hart since 2006, Pink knows better than most what it takes to make a marriage work in show business.

The singer, 41, shared some of wisdom in an Instagram post featuring a sweet photo of the couple embracing and laughing. She described her husband as her "favorite sweet little dirtball" in the post.

"He and I have been at this a long time, and it is our relentless and stubborn idealism that keeps us together," she wrote.

She described marriage as "awful, wonderful, comfort and rage." "It is boring, terrifying, and a total nail biter," she continued. "It is loving another fallible creature while trying to love yourself. It is a lifetime of coming back to the table."

"People laugh at us because we're either fighting or laughing," she admitted. "They roll their eyes when we talk about therapy. But I'll tell you what. It's worth it. All of it. Even when it isn't."

The singer, who has previously spoken about undergoing marriage counseling, went on to note how important therapy is in keeping her marriage together.

"Therapy isn't for weak people or hippies or liberals. It's for broken people that want to be whole," she explained. "It's for runaways that want a family. It's a lesson on how to sit down and listen. How to love yourself so that the other person can, too."

Despite their many ups and downs, Pink and Hart have stayed together and have two kids: daughter Willow, 9, and son Jameson, 3.

The couple's celebrity pals praised Pink for her honesty, with Justin Timberlake writing in the comments, "BEAUTIFUL!" Reese Witherspoon added, "Well said," while Selma Blair wrote, "Perfectly said. Congratulations dirtballs."
