I agree with the getting away thing as a good thing for a marriage, but the other is realizing that no person you are with will be perfect. You must accept the faults of the one you have chosen, and stop looking for a perfect person that does not exist. I think people get divorced or break-up too soon, and miss out on the special bond a long lasting relationship can give you.
The true test for Jeff and Jordan will be when all their fifteen minutes are up, and it is back to reality. I think being in the limelight on two popular shows, and all the attention is like the Bachelor when they go on the hyped up dates. I am pulling for those two, and only time will tell for sure.
