Confused

Am confused i just don't know what to do. i really liked you ever since the start but all you kept doing was playing with my heart. u asked me out once before me smiling my heart full of joy but all that time i did not know u was really being unfaithful
from that day my smile turned in to a frown. you just don't know how much you let me down should i forgive you i don't know what to do but all i know is that i am really confused
