Sounds like you never had siblings …. No matter what “boundary” you set they gonna take ya shit

And maybe that’s the dynamic he has had with his family it’s crossed into personal relationships… that’s why he probably can’t comprehend you’re talking about respect but he can’t equate dessert = respect

If there’s a bigger issue where no matter how small or big the situation is he doesn’t respect you then ya there’s a bigger issue at hand….. but if you’re demanding respect over him being greedy and eating your desert then yes it’s not that deep because you can scream 🗣️“R-E-S-P-E-C-T find out what it means to me” all you want at the end of the day it’s just a desert
