"I was a wedding planner for almost a decade and saw these types of couples regularly. My biggest key indicator for this was whether they cared more about the wedding day than actually being married to one another.

For example, I remember one couple who really wanted an over-the-top wedding that would be good enough to be featured in a popular luxury wedding magazine. They spared no expense. They became so obsessed with this that they were even choosing members of their bridal party based on their looks rather than their relationship with them. The bride had 2 brothers, one brother looked like a model for Hugo Boss and her other brother looked a bit like fat Thor. Well, only the "hot" brother was selected to be a groomsman. Things like this caused a lot of tension between family members and fights between the couple. It was awkward a lot of the time. I knew for sure this couple wouldn't make it for long.

Interestingly enough, the couple divorced a week before their wedding was featured in that luxury bridal magazine."
