Rumors surface but the clear reason behind the divorce of Hollywood ex-couple Brad Pitt and Angelina Jolie has not been confirmed.

Speculations appeared from here and there which included cheating allegations from both sides and abuse accusations, among others. All were denied by the actor's party.

This time, new rumors surfaced that the former lovers had been fighting over some things even before the actress decided to file for divorce that eventually put an end to their two-year marriage.

According to Life & Style through The Hollywood Gossip, the former couple's therapist had revealed that they had been fighting over two main issues that apparently led to the divorce. The two celebrities had both attended therapy for months, before their shocking separation.

According to the aforementioned source, the issues that battered the former couple included sexless marriage and the actress' plan for another adoption.

Reports have been claiming that one of the factors that weakened the couple's relationship was the absence of sexual activity, as per a source.

Additionally, the 52-year-old actor was reportedly not thrilled about the thought of his former wife's plan of adopting a seventh child, and felt un-delighted about having a big, multi-cultured family.

This argument had reportedly made the situation chaotic and that Pitt could not handle it anymore. The source even claimed that the "World War Z" actor had a mental breakdown following the situation with his ex-wife.

Moreover, the actor had reportedly been feeling that Jolie was more focused on turning their family as a model of adoption, rather than actually caring for, and raising their children. This was the reason why the actor had apparently refused on having an addition to their family and argued with Jolie about this.

It can be recalled that the estranged couple are currently fighting for custody of their six children and the actress had been staying in Malibu, California with their kids after the separation.
