Deryck Whibleyhas revealed what led to the end of his marriage toAvril Lavigne.

In his new memoirWalking Disaster: My Life Through Heaven and Hell(out Tuesday, Oct. 8), the Sum 41 frontman, 44, opened up about the dissolution of his three-year marriage to the pop-punk artist, 40, which stemmed from career changes that led to them being physically and emotionally “distant.”

After the punk group released its first middling album which happened to be without former manager Greig Noiri, whom Whibleyaccused of alleged sexual abuse in his book, Whibley found himself struggling.

“There was no single moment or situation that I could point to that caused things to turn,” Whibley writes of his marriage in the book. “It wasn’t like it had been going downhill for a while and turned into a bad relationship. We never fought and always seemed totally in lockstep with each other.”

While he initially tried to chalk it up to a “passing moment,” Whibley needed to eventually address their dynamic.

Whibley was tired of “being humiliated in the media” and hoped that the ultimatum would be “a wake-up call.”

“When she was finally at home for a few days, I laid it all out for her,” the “In Too Deep” musician writes. “‘We have to go back to the respectful loving relationship that we had, or we need to just call it quits,'” I said. ‘This isn’t working and I can’t live like this anymore.’ Avril told me her decision. There was no crying. There was no big fight. There wasn’t even much of a discussion. It was just over."
