Marriage is scary

I just saw this video on tiktok where this old guy is in PUBLIC and he just told his wife he's reponding to work emails but actually he's looking at profiles of half naked women doing a bunch of sexy dances and shit with his brightness all the way up. Like I imagine they've probably been married for decades and the wife has been going about her daily life not knowing about this. ALL those years of your life you spend devoted to someone just for them to do this to you????? It can happen to anyone and that's one of the things that makes this genuinely terrifying. Unknowingly too????? Call me sensitive if u want but I'm scared
