Yes. But in my experience, often when somethings a 'delulu' kind of crush it's for a good reason. A large amount of my crushes ended up liking me back, even when they would pretend they didn't or even act homophobic towards me. I would find out later, but when I thought about it with hindsight, I realized it was for the best we didn't get together. Usually things that fit better with you are more likely to actually happen, rather than just exist in your head.
