the horrible and horrifying feeling of falling in love alone. loving that boy/girl without the satisfaction of receiving their love in return. this experience happens a lot in high school and is often something you wish never happened.
girl: i know we have been friends for a really long time but i really really like you.
boy: listen i like you as a friend and thats it.
girl: but i love you
boy:im sorry it's just one sided love
This type of love does not seem to be mutual, and most people in a "loving couple" tend to discriminate against this, saying it is not a type of love at all. One-sided love commonly occurs when a relationship or marriage breaks, and one person moves on, while their spouse constantly thinks of them and attempts to win them back, often in vain.

John loves Jane. Jane loves John. Jane finds Jake. Jane now loves Jake. Jake loves Jane. John is sad, because he still loves Jane. John experiences one-sided love, even though Jane does not acknowledge that.
