bullet proof..or not?

you might think im bullet proof but im not
i cannot take the way that you are towards me anymore
ive put up with it for way too long
so manytimes ive let it go pretended that i didnt hurt but time and time again you keep hurting me
i dont think you understand what it does to me
when i try to make things better you just make it worse
it turns back on me
i have absolutely no idea what ive done wrong

i dont care anymore
ive thought long and hard and you are not worth the pain
i take a step back
let you go
i told you im not bullet proof
now you know
