Now we see the effects of that whole heart-being-attached problem. Even though the speaker knows, deep down in his heart, that his lady-friend is everybody else’s lady-friend too, it keeps telling him that she has reserved herself for him. Notice that, in these lines, the speaker has stopped explicitly blaming Love for his problems. In fact, from line 7 until the end of the poem, there will be no more mention of Love. Even in line 7, he is referred to only in a fairly indirect way, as "thou," which forces us to think all the way back to the beginning of the poem to remember who the speaker is talking to. Has the speaker changed his mind and decided that the god of Love isn’t really to blame, but rather his own heart and eyes? Who would you blame for this relationship hitting the rocks?
