Mathew Knowles says that it was "difficult" splitting from Beyonce's management team.

In an exclusive interview with the Sun, Mathew revealed his 2011 split from Beyonce was mutual but still painful. “Normally I hate to talk about anything personal, but it would be a lie if I did not say it has been difficult," he said. “It was hard for me to let her go — it was hard for both of us to let each other go. And let’s be clear on that. She didn’t let me go, we both let each other go. That’s a big difference.”

“This was not a normal ending of a business agreement," he told the Sun. "This was a dad and a daughter and it was incredibly painful and it had some difficulties. But I try to always have a positive mind about things and you got to do it the right way.”

Two years ago, Beyonce announced she and her father had decided to part ways. "He is my father for life and I love my dad dearly," the singer said in a statement. "I am grateful for everything he has taught me."

Mathew had managed his daughter since she launched her career as one-fourth of Destiny's Child in the late 1990s, the Los Angeles Times noted. Despite the success of the group, all members eventually severed professional ties with Mathew. He was also previously accused of stealing money from Beyonce, a claim he vehemently denied.

The "Bow Down" singer described the tense fallout in her HBO documentary, "Life Is But A Dream."

"I’m feeling very empty because of my relationship with my dad," she said in a candid, privately recorded video. "And I’m so fragile at this point and I feel like my soul has been tarnished. Life is unpredictable but I feel like I had to move on, and not work with my dad. And I don’t care if I don’t sell one record. It’s bigger than the record, it’s bigger than my career."
