How can Love Burn if it's not Returned?

I was a rebound,
i offered to much heart,
from there i went wrong,
i was screwed from the start,

It started to fast,
i fell so hard,
the first site,
i was like "oh my god",

She was so cute,
smile with dimples,
she had me there,
it's just that simple,

The first conversation,
i knew she was smart,
right off the bat,
i was after her heart,

She infatuated me,
and had me consumed,
maybe the smile,
or her perfume,

I wasn't quite sure,
but i liked the vibe,
i started to see her,
all of the time,

It wasn't to long,
till i fell in love,
and where she sat,
there was no one above,

She was it,
where i wanted to be,
more than i wanted,
i was to blind to see,

I thought she felt me,
like i felt her,
a screeching halt,
it was all a blur,

Now she's gone,
i sit here alone,
just dialing that number,
blowing up her phone,

I knew it was coming,
i could've learned,
what i did in the past,
was getting returned,

I loved her so,
but she didn't love me,
i emotionally crumbled,
when i could finally see,

karma came back,
talk about getting burned,
i lost all feeling,
but i finally learned...
