Literally hundreds of couples on television started off on similarly disagreable terms.

Jeff mentioned Moonlighting in a recent article - also on Cheers, Friends, The X-Files, Battlestar Galactica,  Firefly, Castle even TVD all featured couples that traded insults and snark for years but were actually very fond of each other.

I can appreciate your distaste for the non-canon pairing but it is not beyond the realm of possibility within the show.
