to me this song means that he's in love with a girl he can't have, maybe starting out as friends and she came "too close"...
"if I could bring this plane down now" says that he would wish for this to stop, but he "has no steering wheel".
"has been the saddest lame excuse
to say love me" is just how much he wished that she'd loved him, trying to find any excuse possible, because she's "all that he needs".
