How to stop obsessing over someone: 12 practical steps that help

You can break this painful cycle with highly intentional actions. These twelve steps will guide you toward a healthier mindset.

1. Accept the reality and let go of the fantasy

It’s essential to draw a line between the actual events and the version of the person you’ve built up in your head. It’s easy to fall for someone’s potential rather than who they really are. Being honest about the situation is the only way to let go and genuinely start moving forward.
