Bardon on soulmates?

Did Bardon have anything to say on soulmates, most of what I know is from Kabbalah, which I’ve been taught says we have to let go of attachments and even loved ones.

but my study of Dion Fortune and others like Emanuel Swedenborg say soulmates can choose to remain together even up to the highest worlds where they become as one.

im confused as to why I'm told i need to let go of attachments, i was given a family and emotions, why would i have them to let them go? Isn’t the point that in this realm my emotions are fallen and in the higher realms I’ve my emotions and relationships would be elevated?
