Its a chain reaction. The way I see it, he was sidelined by the industry, maligned using Blinds, his work took a hit with many projects being shelved, pushed to OTT, delayed due to contracts, the #metoo allegation, the media posting blinds, the He was clearly disturbed by getting no validation from the industry, he felt left out and felt alone in the industry.
Then comes the Rhea part, who took advantage of his mental condition, being down and frustrated. That's where she takes him to the psychiatrist ( Mahesh Bhatt;s friend) and then starts the medications, overdoses, and then manipulating him using his fragile mental state.
So he was pushed to this state by both professional and personal life situations
