Pink has moments in her marriage where she "questions everything".
Pink and Carey Hart
The 38-year-old singer has been married to her husband Carey Hart - with whom she has with whom she has six-year-old daughter Willow and nine-month-old son Jameson - since 2006, during which time they have split twice.
And now, the star has said their romance is full of "ups and downs", although at the moment everything is "good again".
She told WHO magazine: "I think when you've been together for a long time, it's inevitable that you will go through times that are really f***ing hard ... there's been many moments where we've questioned everything. That's how we are.
"Right now everything is good again. But any kind of long-term relationship is up and down, and you just take it day by day. Some days are like, 'I love you, you're wonderful'. And the next day you're like, 'I never liked you, there's nothing I like about you. I never want to see you again!'"
It isn't the first time the 'What About Us' hitmaker has spoken of her often tumultuous relationship with the former motocross star - whom she first started dating 16 years ago - as she previously said she sometimes wants to "stab" him with a fork.
Asked how she makes her relationship work, she said: "I just try to laugh as much as possible. And we go through moments where honestly I look at him and I think, 'I've never liked you at all, there's nothing I like about you, I've never liked you, I'll never like you again'. And then five minutes later I'm like, 'You look really good in those jeans'.
"And then two days later he's helping me off the ledge and telling me things that only he could tell me because he's known me that long. And then the next day I want to stab him with a fork. So yeah."
