You should do what my son's girlfriend's parents did. They were high
school sweethearts but got divorced when she was a child. This was quite
traumatic for her. They both remarried and these marriages lasted for
20+ years. Then, each of their spouses died from cancer and recently,
they got married to each other again. How odd. It's like some kind of
dopy Lifetime television movie.
If you're lucky, maybe the same thing will happen to you. Just make sure
that it ain't you and your ex that gets the cancer! That's pretty much
the key to the entire plan.
