i agree with lc52872. also the lines "there's no light at the end of the tunnel tonight, just a bridge that i gotta burn" could mean that this time she's ending the relationship for good, there's no turning back because she's burning the bridge that leads back to him. Maybe he's trying to make her feel guilty (doesn't matter what you do) but she's not falling for it this time (it's what YOU did that's hurting you)
