How does love move and change us?

It just does, since love is an unprecedented aspect of ones life.

Love is like a drug it will blind us and only make us think of one person. its like a hormone that you can't get rid of, it could be love at first sight or you fall in love but it moves and changes us because we find that connection with someone that we don't get with our parents or family members or just friends. its basically just very strong feelings that attract people to each other.
