The 38-year-old has been married to the former motocross champion - with whom she has six-year-old daughter Willow and nine-month-old son Jameson - since 2006, and although the pair have never filed for divorce, they have endured two separate year-long splits.
And the musician has now revealed that she's thankful the pair have learned how to ''communicate'' with one another, as she was growing tired of taking off her ring and handing it back to him every single night.
When asked how her relationship was going these days, Pink said: ''We have learnt the art of communication. I don't hand my wedding ring back every night like I used to. Because that's just dumb and I can't actually get it off.''
The 'What About Us' hitmaker admits she is an ''enabler'' when it comes to the rocky moments of their 16-year relationship, and says the main problem they face is that they both have strong personalities.
She added to Australia's '60 Minutes': ''I will lawyer the s**t out of him. I take it to court and I want to talk about each little point before we move on, and he just gives up.''
It comes after the 'So What' singer joked earlier this week that she sometimes wants to ''stab'' her spouse with a fork when things are rough between them, but said the key to making it work is to ''laugh as much as possible''.
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.''
