My boss expects me to treat him like my girlfriend ffs

I recently made a switch and joined this remote organization. Off late, I’ve realized its a bunch of scammers and pseudo-visionaries who are running that shitshow. Surprisingly its a large company and money is flowing in. I report directly to the CEO and he expects me to ‘nag’ him or ‘spam’ him all the time with WA texts. G**ndu wouldn’t reply to my texts for days at a stretch, won’t reply to emails but call me out in a company townhall saying he didn’t hear any update. When I pointed out that I’m waiting on his feedback, his point was that I didn’t escalate! Who tf do I escalate about the CEO to? And why is it okay to expect an employee to spam on text messages. Don’t you want them to respect your time ffs? Goes on to only say how he doesn’t value his own time. Now everytime I get a WA notification, my anxiety spikes up. Is this toxicity even normal and acceptable?
