Have you ever deluded yourself into feeling something?

For example, have you deluded yourself into being in love or having feelings for someone, later realizing your feelings weren’t true? If so, how did it make you feel? It’s happened to me, and it’s a very scary realization… to think you were so resolute in something that simply turned out to be false. Maybe you didn’t have a full understanding of the person, or your desire for love/a relationship created false feelings, or you were won over by superficial things like physical attractiveness and flattery. Either way, you just look back and are shocked at how misled you were.
