I thought you were a best friend

Till the day that you hurt me.
literally ripping out my heart.
I thought you were my best friend,
Right from high schools start.
Now you choose to friend end,
as your words and actions have now spread us more than worlds apart.
I'm talking decimation of a best friendship,
just because I finally stand up for myself,
Our friendship now,
It has to part.
There's no point in putting the keys back in at any point in the future,
as our friendship engine,
will never again start.
I'm sorry I've lost you,
Even though you're an arsehole. An upstart.
you've even gone running with you tail between your legs to my mother.
Really?
Did you think that was smart?
Just shows that you're the guilty oneas going to mine own mum really is quite low and dark.
25 years of a friendship,
that's lost our brotherly spark.. I'm not going to stand idley by though,
whilst upon my fiancée,
an argument sparks.
All from the venom coming out of your mouth,
Get your facts right for a start.
stop trying to come between my loved one and I.
stop being an arse of a shauvanistic,
complete upstart!

Think before you type.
As I don't want to hear it,
if any kind of gripe.
any kind of detrimentalism,
Any bad feelings or even evil you invent.
Positivity is what I need in my life.
not your dramas,
As you leave my mind boggled and spent!
why come at my fiancée like that,
you snakey serpent.
Best friends?
My arse.
​​arse.
If that were the case,
Then hurting my partner,
wouldn't be full of intent!

You've a lot to answer for,
Yet you never will.
Ewillif on your deathbed,
As your worlds so surreal.
whatever is in your head,
To you,
It's real.
So come on then,
What's the big deal?
Why have beef with my fiancée and expect me to have,
No anger appeal.

You're A 'Melt',
you're a fool,
You're a dickhead of a tool.
You're not better than anyone,
and you think how you treat women,
Really is cool.
I've nothing else to say to you.
except to move on,
Before I lose my rag,
My inner,
stormy whirlpool.

So jog on.
Take a.hike right out of my life.
Don't look back,
As all you cause me is strife.
Anyway,
How could I be best mates or even friends,
if you can't even like or respect my future wife,
who'll be with me till my demise, 
My end!
