Is relationship without marriage not considered serious? I would say any kind of commitment is getting serious, while casual sex isn't. If someone said to me "im not looking for anything serious" i would never assume he wants companionship, rather that he wants to play around and leave at any given time.

A guy would say "I am looking for companionship" if he is looking for companionship.
