Unkillable Monster

The part about being a tightrope walker reminds me of the first part of Thus Spoke Zarathustra by Nietzsche. Look it up if you're not familiar with it. Basically, the "tightrope walker" is used as a metaphor in the book where a jester (who is similar to Zarathustra) is able to leap over a man walking on a tightrope, where the rope is symbolic for man being the bridge to the Ubermensch. When the jester leaps over the man, the man falls to his death. It's like a parable. Zarathustra's goal is to lead man to reach his true potential as a species, to evolve into a better race. Zarathustra is urging man to hurry accross the bridge that will lead them to their ultimate supremacy, but in doing so many perish, because the bridge to the Ubermensch is a long and dangerous one, man must be surpassed.

I think it's about trying to end a relationship. About being the one to say goodbye and trying to end everything smoothly without hurting anyone's feelings, because you still love them, but for whatever reasons things just aren't going to work out. You try to give subtle clues that the relationship should end, but she doesn't respond (You refuse to die). You try to push her away, but she still doesn't just stay away. Instead she stays and calls you a monster for treating her this way. He dreams about being able to kill her (not literally, just to be able to make her go) without hurting her (the prettiest death I know). What he means by "my wound is a front door to you" is that his pain only makes her want to stay, because she feels sorry for him and guilty, instead of just leaving and ending his pain. "Am I my own shadow" shows that he is confused and is second guessing himself. The "shadow" is a term in Jungian psychology that refers to your inner, deeper, darker self; the dark side of you. He's saying "maybe I really am a monster, maybe she's right." The rest I think is pretty self explanatory.
