Madonna felt "incarcerated" while with Guy Ritchie.
The 'Living For Love' hitmaker has confessed to feeling trapped by the 'Sherlock Holmes' director during their seven-and-a-half-year marriage and believes the 46-year-old filmmaker held her back artistically.
Speaking about their time together, she said: "I did find myself sometimes in a state of conflict. There were many times when I wanted to express myself as an artist in ways that I don't think my ex-husband felt comfortable with.
"There were times when I felt incarcerated. I wasn't really allowed to be myself."
The 56-year-old star - whose 13th studio album 'Rebel Heart' is out this week - divorced Guy in 2008, but now acknowledges compromise is a key part of any relationship, so she just needs to find the right man who can fully accept what she does.
She told The Sun newspaper: "I think when you get married you have to be willing to make a lot of compromises and that's fair enough. I think that's the way it goes in relationships."
The iconic singer - who has sons Rocco, 14, and adopted David, nine, with Guy, as well as Lourdes, 18, from a previous relationship and Mercy, nine, who she adopted alone - added: "It doesn't mean that marriage is a bad thing. But if you're an artist you've got to find someone who accepts who you are and are comfortable with that."
