That's my main argument against flexitarianism. You can't be "kinda vegan" without leaving your brain in permanent stress due to dissonance. It's part of what stops me from adopting an animal, specially a cat.
To be honest, a lot of meat still tastes kind of gross to me. Give me fried tofu over baked chicken in a salad. Heck if I’m just having a a boring burger for a random lunch on a Tuesday, give me an Impossible patty over some crappy fast food beef.
That said if there’s a dish that’s enhanced by meat (say a Wagyu steak or a pastrami sandwich) then sure, I’ll eat that a few times a week.
At least so far, this hasn’t caused me any stress.
