How is it?

How is it that you manged to cheat on me?
how is it that you managed to break my heart?
you tore it right apart
this is only the start of the pain i will feel
and right now i cant believe this is real
i told u i didnt wanna fall in love
but you let me
i told i didnt wanna get hurt
but you hurt me anyway
and you expect me to stay?
i have no idea what to say
all i kno is i dont wanna be with out you, but ur acting like a fool
you see this this aint even cool
i dont kno if you think that you can play me!
but you cant
and how is it that you manged to lie, when you promised you wouldnt?
how is it I let myself fall in love even thoa i shouldnt!
i cant belive
so how is it i cant even mange to leave?
