I think he just ended a relationship for an unmentioned reason, and can't decide whether or not it was the right thing to do ("No matter what you say, you can't convince yourself this is the right thing. It's not the right thing.").
I would say the girl ended the relationship, but the lyrics say, "One last chance - I reject your call." He's the one avoiding her.
I'm guessing he finds his decision unbearable, because he still loves her*, and death sounds oh-so sweet ("The plane, it banks. We begin to fall. This is the best dream I've ever had."). I wouldn't say he regrets his decision, though, or he would have answered her call.
"As long as we are choosing sides, I think its only fair I have the right to make the first round pick, and you should know that you're still it."
Whatever's being referred to in "choosing sides" is probably the reason for the breakup.
