Yeah that's why maybe a "Fred and Betty" marriage would NOT work out, having 2 dominant people married..I recall 1 episode that Betty was cooking for Fred and she stared critizing her cooking and pratically kicked him out of the house, He critizises Wilma all the time and she pretty well takes it.
It might be kinda like a "Dan and Roseanne" marriage:)

But I think Fred and Betty would have had happy times too, b/c say what you want about Fred Flintstone, he may be loud and ridicolous at times but he was a charmer and a romancer at heart. I think Betty would have liked that. Barney didn't seem all that romantic.
