Shouldve Known Better

i thought that we could make it work, you acted like you were changing, but i shouldve known better. you told me you were ready to get serious, and that you had grown up and matured, but i shouldve known better. i gave you my trust and my heart, i made you my everything, but i shouldve known better. i believed in you when you just lied, i stayed with you when you just cheated, but i shouldve known better. now im letting go, cause i cant hold on anymore, i shouldve known better that to fall for you.
