Throughout heaven, people who are similar gather together and people who are dissimilar part company

When people who were married on earth meet again in the afterlife, if they were truly of one mind, their marriage will continue in heaven. However, if the two people were not truly compatible, they will gradually separate of their own accord. “Throughout heaven, people who are similar gather together and people who are dissimilar part company.

This means that every community consists of like-minded people. Like are drawn toward like not by their own will but by the Lord. In the same way, spouse is drawn toward spouse when their minds can be united as one. So at first sight they love each other most deeply, see each other as married partners, and enter into their marriage.” 

Swedenborg describes both betrothals and marriages in heaven. During the course of a marriage, because of the way that people’s minds are open to each other in the spiritual world, the partners gradually enter into each other’s thoughts and affections until they become like a single person. In fact, Swedenborg says that “two spouses living in heaven are not called two angels but one angel”
