This is what the urban dictionary has to say:
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.
Now a question arises:
Does one sided love ever work?
Lets see what WikiAnswers says:
