Dean McDermott and Tori Spelling

Tori Spelling's husband is quitting reality TV.

Dean McDermott, who has been fighting to save his marriage since admitting he cheated on the former 'Beverly Hills 90210' actress late last year, no longer wants to share his "thoughts and demons with the world" via their Lifetime series, 'True Tori,' after contemplating suicide.

The 'Chopped Canada' host, 47, said: "We have five more shows left. I can't do this anymore. I can't keep opening a vein, opening my soul and sharing my feelings and thoughts and demons with the world. I don't watch it. I can't. It's really difficult. I can't do it anymore, for my soul."

Dean, who battles depression and sought treatment in rehab earlier this year, also admitted he was secretly placed under an involuntary psychiatric hold in a Los Angeles hospital after having suicidal thoughts, but his doctors have since adjusted his medication and he is determined to get his life back on track.

He now wants to focus on repairing his relationship with Tori, 41, and caring for their four children, Liam, seven, Stella, five, Hattie, three, and Finn, two, behind closed doors.

He told 'Access Hollywood': "The fact that I cheated on my wife, I wish never happened. I wish my alcohol and drug use hadn't gotten out of control. I still love her to death and that's why we're still together.

"I almost lost everything, everything that means anything to me. I don't want to ever do that again. I don't ever want to be in that dark place again where I wanted to take my life.

"I hold out a lot of hope. If you don't have hope what do you have? I love this woman, regardless of what I've done. I love her and want to be with her."
