Stayover relationships

OK, now I'm confused. For years, we heard about how young people are delaying marriage and simply living together for an extended period of time.

Now, young people are apparently still delaying marriage...while embracing "stayover relationships."

Those couples spend at least three nights a week together, but live in separate homes. This article describes the phenomenon:

Having both convenience and independence is a major draw for young adults who choose to stay over instead of cohabiting, Jamison found through interviews with 22 college-educated young adults in committed relationships.

And getting out of a relationship is easier for couples in "stayover relationships," since they don't have to worry about a shared apartment lease or other major elements of their lives that are bound to each other.

I've been in a "stayover relationship" for about five years. The setup has drawbacks, but it's also kind of awesome at times. Such is life.

What do you think about the setup?
