He’s never been called out on his bullshit and had it stick until last year.
Excellent post.
That's exactly why he's built up such a bulletproof shell of self-confidence and aggrandisement. Noone had really challenged his image of himself for all this time until last year. He's still in the denial stage where he just can't bring himself (publicly at least) to really admit he may have been wrong and been the bad guy at any point. That denial may continue forever or, as TonusOH said earlier, he may have a sudden epiphany one day which will either break him or it will solidify his position as a real villain with a chip on his shoulder.
He thinks he’s the best thing to have ever happened to Dijana and probably wastes no time in reminding her what a local brother in Sisak would have earned for her.
Don't forget also, the other tactic used by many adulterers, cheaters and sex offenders: blame their partner's supposed inadequacies for their perversion or choice of infidelity. In his case, he blamed her inability to satisfy him for his "need" (ie: deliberate choice) to pursue prostitutes on a regular basis.
That's almost the ultimate betrayal, not just the act of cheating itself, but to undermine your mate by publicly blaming her alleged faults for your problems. Add to that the repeated mental attacks on her with manipulative, gaslighting messages and the use of his kids to massage his image and there is no doubt he is a toxic husband and father.
Will he ever realise that either? And would that realisation even make him change? Who knows. But right now, the indicators are not positive.
