Miss placed trust?

What is my she thinking
What I have heard has left my heart sinking
This guy is not good
He would have his way if he could
He has stolen and violated
And now my trust has been eliminated
He tried to feel a woman twice his age
And then my own sister who is the same age
He stole from a house with kids
Yet my sister says he harmless like a kid
I wanted him to make the one I love happy
But he now seems the type to make her unhappy

People rarely change there inner thoughts stay the same
I know this I have seen is so often it is a shame
So many falsely believe they can change another
Instead they get devoured by the others
who put on a innocent mask
So that they can get to their task
Of using the other for their dark fantasies
they care nothing for the others insanities
I know their actions all to well
I used to be like them until I fell
Shattering everything but the mask
So I slowly began to feel the lies of the past
The fake emotions I showed now last
Instead of fading into my dark mind
The inner heart is what they now find
Slowly they changing it
Into something that will not fit
It wants to grab hold and protect
Another but I am just a reject
