Most Helpful Guy
I've herad many such stories, and it is very common that people who have divorced, for example, continue to have a relationship since often it's difficult for either of them to find someone else, and they are USED to each other..
jThey are over all the adjustment phases in a relationship, that are so difficult in a new one...and finding a new one, especially when you are out of your college years, is so difficult!
So yes, your story is far from uncommon. Eventually one of you will find someone they like, and then your break-up will be complete. It won't be a difficult break-up since, as in your case, the two people no longer have a lot of emotional commitment to each other, and both know that they are only staving off loneliness, until they, hopefully, find someone they'd like to really 'be' with.
As you say, this is a situation without 'grudges' or false expectations. That's pretty hard to find in the real world! I can see why people want to stay where they are safe from those problems, at least! I thought it was weird when I first heard about such an arrangement, but by now I've heard so MANY similar stories, that I can see for many people, it's not a bad alternative.
But there are of course down sides, such as the high probability of gettiting an STD, since one or both of you are probably regularly sleeping with other people..something that hopefully isn't happening with a 'real' relationship.
