The Unrequited Love (On-going)

"To be loved, is to be known." I've heard that many times already but until now I still don't know how to define the meaning of it. How will I know if I am loved? how will I know if I am known? is it by the way they say these three words often to fulfill the feeling or thought of being loved? or is it by giving and receiving gifts? playing with their hair, singing them a song, or is it cooking their favorite dish? it's hard for me to know how and when but I am sure of one thing, we tend to seek answers from others that are meant to be answered by ourselves.
