Accept that the feeling is real, but the fantasy is not a relationship
Cut contact with the person as much as possible
Stop checking their social media, messages, photos, and updates
Remove reminders, triggers, and saved content
Do not rehearse conversations or imagined scenarios
Interrupt obsessive thoughts immediately and redirect attention
Keep a written list of facts about the person, not fantasies
Notice idealization and replace it with reality-based thinking
Avoid mutual friends’ updates and gossip
Fill your schedule with work, exercise, hobbies, and social plans
Strengthen other relationships and spend time with supportive people
Practice mindfulness and grounding when urges to ruminate appear
Limit alcohol and other substances that lower self-control
Sleep regularly and maintain basic self-care
Set firm boundaries with yourself about contact and checking
Journal triggers, patterns, and emotional needs behind the fixation
Work on self-esteem and attachment issues
Seek therapy if the obsession is intense, persistent, or disruptive
Treat relapses as setbacks, not permission to restart the cycle
Focus on building a life that does not center on one person
