Last year I had a brutal crush and confessed like 3 months after meeting her. Rather than throwing the baby out with the bathwater, she was polite and kind yet firm about the necessity of me killing my feelings, as she still wanted me around but just as a friend.
I can't say that it was easy for me to get over those feelings as I was very much in a state of limerence, but I knew that she was worth having in my life, even if it wasn't in my idealized form.
Fast forward to now and we are best friends and deeply important people for each other. I'm so grateful to her for not throwing the baby out with the bathwater when I confessed, and leaving the ball in my court. Getting over those feelings was worth it ten times over, and what I thought was love for her last year is incomparable to the platonic love we have for each other now.
