How could this be?

How could this be?
You shown me the true meaning of happiness
Within a day you took it
away
Since than you have never been the same
Changed drastically
Broke up with me multiple times
ripped my heart out
Now im numb
Not only that youve asked for me back
Not once or twice
plenty of times
Why?
I can't answer that
Only because I see no changed
No effort in why I should take you back
Your just going to do same crap
And it'll always the same result
I love someone who doesn't deserve my love
Letting them stay in my life longer than they should have
Someone who's just going to point the finger
Make excuses
Be the victim
Instead of being a mature woman
Give a true genuine apology
Talking things out
Give what they expect
How could this be?
My happiness made me unhappy
Made me the outsider like everyone else
I don't belong not even with her
She deserted me
No where to be found
Sad to say
my monster is the woman with my heart
She the monster who corrupted my heart
Feeling like a scarecrow
Ugly with no heart
How could this be?
How could this happen to me again?
Am I horrible?
Am I meant to be alone?
Am I that bad?
How could my happiness end my happiness within one day?
Why me?
Why can't I be loved?
Am I disease?
Am I not worthy?
What is it?
Im not perfect but I haven't done wrong
Why do you treat me like im the worst?
So many unanswered questions
Just to be in shock
And ask myself
How could this be?
How could you do this to me ?
