I personally strongly think that its a love song. The singer is saying to appreciate every moment with the one you love because you never know when you will lose them. This person is scared to fell in love. And that this person didn't realize how good of a bf or gf this person was. And everytime that person had their love they would let them go. And now they finally realized that they really loved them the whole time but its too late and they can never have that person back and all they have left are moments that are forever dead.
