I cant let him go

I know this is wrong
because I'm promised to another
but i just cant let him go
its the way he makes me smile and feel loved
when i just wanna give up
its how he treats me
like a princess
don't get me wrong
i love my prince charming
but this other guy
i adore him
and how he acts to wards me
its how his feelings are true rare and so pure
i cant let him go
but i cant be with him
because I'm bond to prince charming by my young and foolish heart
when I'm with prince charming
its heaven
but when were apart we fight and its hell
and then there comes this other guy who picks me up when i fall
holds my hand through tough
feelings so strong
how can they be so wrong?
i know this isn't right.
but i just cant let him go
