What would someone know about love if he has never loved before?

I think blind loving is heart-breaking. and it is also laughable.
unconditional love is bs, especially if it's one-sided. anything that people say to prove that wrong is only to make themselves feel better about not being loved in return. it is sad for them, and it is sad for people watching. the only happy one is the oblivious idiot who is unknowing causing pain.
but then, what do I know?
it is just agonizing to watch.
