Yes, men who have children do go through nihilistic existential mid life crises too. That age has their biggest risk of cheating on their partners, fathering new children with work colleagues, walking away from marriage, developing drug and alcohol dependency, developing serious gambling problems and other worse things. Parenthood reduces but does not eliminate the risk of suicide in middle aged men, and parenthood plus long term joblessness is a common cause.

Midlife anxieties are real and nothing in particular prevents it.
