Release the need to control
One of the reasons people overthink relationships is their need to control the future. They’ve found this relationship which they value and don’t want to end, and as a result, they stress over the tiniest of things in hopes of preserving the relationship. Of course, it’s impossible to control another person and future outcomes. Further, overthinking can actually have an adverse effect on relationship longevity. Meditation is a great tool that can help you to live in the now and cease your attempts to control the future.
