Lyric discussion by Kleiny 

The lyrics that I am looking at are accurate.

"in pitch dark i go walking in your landscape. broken branches trip me as i speak."

Clearly he hasn't done this before, and it's the ragged road of infidelity that will bring him undone, which he knows.

"just coz you feel it doesnt mean its there. just coz you feel it doesnt mean its there."

This is an assurance from him that any feelings they may have, may not be real.

"There's always a siren Singing you to shipwreck (Don't reach out, don't reach out Don't reach out, don't reach out) Stay away from these rocks We'd be a walking disaster (Don't reach out, don't reach out Don't reach out, don't reach out)"

The Homeric reference is immediate; If I follow my insincts (which is to be drawn in by beauty) I will suffer.

"just coz you feel it doesn't mean its there. (theres someone on your shoulder) just coz you feel it doesn't mean its there. (theres someone on your shoulder)"

No longer singing to her, but himself.

"why so green and lonely? and lonely and lonely heaven sent you to me to me to me"

Despite all of his warnings to himself, he's now starting to justify why it should happen.

"we are accidents waiting waiting to happen. we are accidents waiting waiting to happen."

Finally he surrenders to fate, he can no longer justify keeping himself or her apart.
