What does she have that I don't?..

You say you want someone who will be trustworthy and will never lie, someone who will never cheat.
she cheated on you many times,
so now that were together... You can't even trust me.
I give you all my love and cherish you,
while she cheats on you with her ex foo.
you tell me that you wish she was as honest & straight out like me,
but when I see pictures of you too kissing,
man... Not only does it break my heart,
but I'm tonr apart. Again.
when you're with me,
you tell me you feel happy and like it's just us two and no one else,
but when you write stuff about her on your page, you say things that not even I myself have never even felt.
what does she have that I don't?
