Summarize this article:

Your crush might linger if you daydream about what could be, but holding onto your fantasies will only lead to more pain. Accept the reality of the situation and your feelings of attraction equally. Gradually avoid thinking about what your relationship would be like if it could only work out.  Don't dwell on the past or worry about the future. Instead, ground yourself in the present.  Instead of building up a fantasy life, work on yourself. Set goals in your work or hobbies, spend time with loved ones, and work on self-improvement to love the life you have. Your friendship with this person can still be meaningful, even if you can't pursue a romantic relationship with them. Think about all the good times you've had with this person and the positive qualities they have. Have gratitude that this person is in your life and that you've had the opportunity to know them. You don't have to stop being friends, but spending time with just this person can cause you to dwell more on your feelings. You might need some time away from this person to work through your feelings. Tell your friend that you need space for a while. While you're spending time away from them, focus on other things, like trying a new hobby or meeting new people.  Rebuilding a friendship can take weeks or months. You may not feel "over" your crush until you find someone new. Take as much time as you need to process your emotions. Let your friend know why you need space so that they don't feel hurt or confused. Let them know that it isn't their fault and that you still care about them. If you want to fall out of love with your crush, set boundaries for yourself and your friend to avoid sparking old flames. You might avoid extended physical contact with your friend, stop flirting with them, or steer away from intimate conversations for a while. Share the boundaries with your friend (if you're comfortable) so they know to avoid those situations.  For example, you might tell your friend to hold off on the cuddling or hugging, even if they just mean it in a platonic way. On the flip side, you may have to hold yourself back from hugging or holding them. Let them know why you are doing this so they don't feel hurt or abandoned.

Summary:
Separate fantasy from what actually is. Appreciate your friendship for what you have. Spend some time apart for a while. Set boundaries.
