To me, it's about a guy who is in love with a girl who feels as though she no longer requires him in her life, and he feels as though, he will be there waiting for her, because he knows in his heart she can't live without him hence don't miss your water (because u cant live without water). It sounds like she is tested from what her friends, her family tell her about this guy, how there not meant to be together and if she strays, she doesn't know what she's lost until it's gone, but he will be there through the good and the bad times no matter what.
