It isn’t scary.
It is scary when people get sick, because then you think that could haappen to you.
It is scary when people are killed or injured in accidents or attacks or crimes. Same reason.
It is not scary when people get divorced. If you don’t want to get divorced, be honest with the people you date, and be honest wwith yourself, and marry someone who you think is good for you, and then work on your marriage.
I’m not saying divorce is a choice. But it is usually the culmination of a lot of previous bad choices.
