问世间情为何悟？

Confused. Are you the reason? Or is it me myself? Love and being loved, it's just so unjustifiable.
"It's always to be loved than to love someone"
Would you choose to love or hope being loved by someone? Why I say unjustifiable is because, say:

Example A: You love A, but A doesn't put in his efforts in loving you back, how will you feel? Will you continue to love this someone? Will it be fair for only you to continuing loving to get none in returns?

Example B: A loves you more than you loves A. The things & efforts A do is more than what you will do for A, will start loving A and appreciates it?

In love, who doesn't hope to be loved than to love someone? To love someone always mean the extra efforts, commitments, and doing things willingly for that special someone, but it can be tiring. Having to be appreciated kills and subside the tireness, it's becomes WORTHWHILE. But to love someone without being loved back, it deficts the reason why humans need to LOVE.
