What is the meaning of Love?

“So along you came and first I was blind. To see that God sent me to you, the person I was meant to find. My guard was heavy, but you just felt right, it did take me while to see you in first light, but now, life without you, I cannot seem to fathom, life without you, I cannot seem to imagine, life without you I could not go a day, a life without you, is a life wasting away” Matthew.
