"Love me, Love me, say that you love me,"

Kurt was completely and utterly obsessed with you. His mother always told him to stick to someone that fully deserved him and his traits, and he believed that was you.

"Fool me, Fool me, go on and Fool me,"

He didnt care if he was a fly constantly going into your trap. He loved you, even if you didn't reciprocate the feelings as strongly. He just needed you.

"Love me, Love me, pretend that you love me,"

He just needed to feel as if you loved him and wanted him just as bad as he wanted you. You had became his prime obsession, and his only living source.

"Leave me, Leave me, just say that you need me,"

He didnt care if you left him, as long as he got some form of affection or attention from you, then he was happy to be in your presence at all times.

"I can't care about anything but you."

He just needed you to know that he felt this way, and that his every thought was about you. He was completely devoted to you, and the love and happiness you brought to him.
