When a relationship is serious, it’s common to define it as long term [1] in order to qualify its significance. But what does long term really mean? Chitchatting with some girlfriends the other night, I realized that we all had a different length of time that qualified as long term in our books. For some of them it was only a few months, but one was a stickler for length — she said two years! So what about you? Do tell, how much time has to pass before you consider a relationship to be long term? Or does it have more to do with the seriousness than any set amount of time?
