This guy is the one from Russia who makes Carrie move to Paris. He's guilty of enforcing his own values of 'men being the breadwinners of the family' onto her own plans and ambitions. Basically he wants her to be a stay-at-home wife. In Miranda's words, "I want to enjoy my
success, not apologize for it," and that's just what Carrie ultimately decides to do.
She doesn't get away from this controlling dude fast enough to escape his fist, unfortunately. In one passionate argument in Episode 20 of the show's 6th season, he lays a hand on Carrie. That's the lowest of the low, making him the least dateable person on this list.
