When love sucks..

I don't know what to do anymore.
Everytime i let my guard down, hoping for something good
to come my way, hoping no one will hurt me, it never ends good.
I turn around and realize how foolish i was when i see that
you're with someone else.It seems like it was yesterday that you said that you loved me and wanted to be with me. Now that i've let down my guard, in hopes that you'd come to make me complete, i can see how foolish i am.
Once again, i'm left asking the wall if there's something wrong with me.
I look for you, but all i see is the shell of the guy who claimed
that he loves me, but now is holding another dear to him.
Is it because i'm not abusive?
Is it because i'm kind and caring?
Is it because the thought of cheating on you never once has crossed my mind?
Please tell me.. I feel like i'm going insane! I feel like the only
thing for me to do anymore is exist in an empty body in hopes
that someone will come along and love me. But now i realise that
my dream is all lies and no one will ever love me for who i am.
