Accept that the crush is real, but the relationship may not be
Limit contact and reduce checking their social media
Stop feeding fantasies about what could happen
Remind yourself of their flaws and incompatibilities
Stay busy with work, hobbies, exercise, and friends
Avoid situations that keep reopening the attachment
Talk to someone you trust about your feelings
Write down what you want in a real partner
Focus on building your own confidence and goals
Give yourself time to detach
If needed, create firm boundaries
Be open to meeting new people when you are ready
