Search Results: how i can win him back

I recently had an ex get in touch wanting to be friends and come to a show my band did this weekend. With my luck we happened to be playing the song I wrote about her and our break up. Before the show I told her about it and played her the song.

She flipped, called me insensitive and a lot of other names, I'm just curious if maybe I was in the wrong or if she really did overreact.

The lyrics:
Now you won’t even pick up my calls
Instead of you, I hear a dull voice
There are always hard days
But you can’t win over that moment and you look for an alternative

Let’s take some time
When I heard that
I took it exactly as it sounded
We should take some time

Congratulations, you’re so amazing
Congratulations, how could you be so fine?
How could you trample on me?
I see your smiling face, I guess you forgot everything
When you said let’s take some time
When you said let’s think about it
You looked into my eyes and made me believe you
Like this

How could you be so fine?
How could you trample on me?
I see your smiling face as you completely forgot about me
As you’re being so happy

How is he? Is he better than me?
Did he erase all your memories about us?
Yeah, your happiness is all that matters
No, I’m not gonna tell a lie like that
Why should I wish you happiness
When you’re the one who left me?
I don’t give a-

Seriously wow girl congratulations
It didn’t take you long, you’re such a hotshot
Huh, I saw your pictures
Are you really that happy?
For me, my heart still hurts every time I breathe
But it’s good that you’ll never be in pain
Because even if you break up with him
You’ll just find another one

Congratulations, how could you do this?
Congratulations, you won’t ever come back to me
I don’t even expect it
I don’t know how well you’ll live without me
When you said let’s take some time
When you said let’s think about it
You trapped me inside this waiting
And only you are free

Leave me
Go to him
As if a guy like me never existed
You’ve fallen in love

... Who's wrong?

Let's say there was an officer shooting to kill even though you genuinely didn't do anything wrong.
His reasons could be
He thinks you're trying to harm him
He is mistaking you for somebody else

For whatever reason he's shooting at you trying to kill you
If you shoot back defending yourself & possibly killing the policeman,
Would you win this case?
