I love it Ben! Well done on getting down to 9.2%, and great idea on the photo shoot!
Yes pretty much all long-term couples have gone through it, are going through it or will go through it. I honestly don't know a single exception. I've known couples that were together for 50+ years that went through terrible times. No one is immune. I think older people come from a generation that held marriage in higher esteem and tended to work harder to make things work out despite the rough times. That's why the divorce rate used to be lower. It wasn't because they had perfectly happy marriages, it was because when they went through the loss of love and associated fallout they both committed to working hard to get it back on track. Unfortunately these days marriage is not held to the same standard it used to be, so WAS's are encouraged to walk at the first sign of trouble.
