None of this dismisses the fact that this is a grown man who resorts to escapism and infidelity rather than owning his marriage and taking the necessary steps to correct it.
I still say most of this "for three years" garbage is script.
Sure, he may feel hurt, but I think this man has GUILT running through him, STRESS, FRUSTRATION, FEAR, EMBARASSMENT and a myriad of other emotions.
He seems to think he has this marvelous talent to compartmentalize all of this and isolate the exact cause of each of his feelings to one person each.
Wow, that's impressive!
He's found his true self?
His true self is a liar, a cheat, and a deadbeat child who wont' own his behaviour?
Man, that's someone I would be proud to be one day!
