No better place to come for therapy than USMB but if he mentions his mother I'm out of here.Are you speaking from personal experience or just making stuff up? I'm sure you could find examples of such behavior but I doubt it is very common.Middle age men wreck their wife's finances all the time so that she will divorce him. That leaves him free to have sex with all kinds of honeys. Men start panicking at a certain age when they think they are very close to becoming too old to chase hot honeys.
He seems to be struggling with the situation he has found himself trapped in. He is surrounded by Christians and says he's an atheist yet professes a religious perspective on morality. His talk about multiple sexual partners and chasing "hot honeys" makes it seem like he secretly wants to pursue what he has been persuaded to believe is deviant but lacks the 'faith'..
Sounds like quite the dilemma.
