Relationships have their highs and lows, and TV couples aren't exempt from the norm. Television couples bicker for various reasons, whether they're in a healthy relationship or a toxic one.

Other couples fight endlessly back and forth because they begin as enemies but eventually turn to lovers because they cannot deny their chemistry.
