Bullet Proof Lyrics
My two cents:
"Swim, the tide is coming in. We spent too long watching Bullet holes rushing in. No use bailing."
The singer is speaking to her partner about how this relationship is at a point where they both need to address the issue of "bullet holes", which to me means that the partner has had too many other lovers or the likes, but for "the wrong reasons" so to speak which in turn has left the partner cold. It needs to be addressed now, it cannot wait.
"Bullet Proof: They never loved you. You let too many bullets through."
The partner has been seeking this many lovers due to personal issues. These lovers has made the partner feel strong and confident, but in reality, it only underlines why they are broken inside and thus leaving them empty inside. So while being bullet proof (meaning not letting anyone in) they are also damaging themselves, by being too cold and distant.
"To be patient and awake. There are things to learn here Kate: To forgive and to accept Things that haven't happened yet."
The singer is telling the partner (apparently named Kate) to change their ways and start to accept whatever it is that made them this way. And also, as in every relationship, to accept that there will be issues (maybe similar to the what the partner has experienced before) and that this is okay.
"Bullet Proof: They never loved you. You let too many bullets through."
The singer is telling the partner that all the lovers he/she has had never loved him/her, it never about emotions. This refers back to the lovers being bullets going through, making the partner not actually bullet proof.
"Everything we broke today Needed breaking anyway. But can you prove to me That you can feel anything?"
Addressing this issue is devastating, meaning that the partner's self image has been shattered or the likes. But this is necessary in order to let the partner evolve and overcome, hence why this "needed breaking anyway".
"Prove to me that you can feel..."
Pretty self explanatory. The partner needs to show that they are actually able to let the singer in if they want to move forward together.
