As near as I can tell, he saw this girl, and said to homself, "Wow, she's the one for me." He gets all prettied up and they become close. Then she tells him that, either, "There's more people out there than you, and you're not the one." Or, "I can do better than you." Either way, he's crushed and he loves her very much. He remembers all the stuff and fun they used to have, and whenever he sees her, it kills him because he misses her so much. In the last verse he asks her to stay with him, he will love her unconditionally, he can show her that he loves her, and how much she makes him feel alive.
