The 47-year-old reality TV star is tired of his actress spouse - with who he has children Liam, seven, Stella, five, Hattie, two, and Finn, 20 months - ''playing the victim'' following recent revelations he had cheated on her, and though she has stood by him through the scandal and subsequent rehab stint, he is said to be ready to pull the plug on their seven-year marriage.
A source said: ''Dean has finally had enough and he is tired of Tori playing the victim.
''Yes, Dean cheated on her, but Tori definitely played a role in where their marriage was when that happened. For months, Tori has railed on Dean and he has taken it. However, Dean has had it. Now he is threatening her with divorce.''
And Dean is said to be particularly unhappy with Tori's decision to film 'True Tori', her latest reality show in the midst of their difficulties.
The source added to RadarOnline.com: ''There was a time when Dean would have done whatever Tori wanted, but this has gone too far.
''Publicly shaming Dean is one thing, but their four children are going to be able to watch the show when they are older and that really distresses him.''
However, the 40-year-old star is said to believe Dean won't follow through in his threats.
The source said: ''Tori doesn't think that Dean will actually pull the plug on their marriage.
''In her mind, she is the only one that can decide whether or not they will split up. She could be in for a very rude awakening.''
Gendry has been living under Cersei Lannister's nose for quite some time now.
The director would love to take the films in a different direction.
He'll be performing a new residency at an intimate theatre.
