“She and I studied at different schools at the time.
I was on a school trip in a nearby city.
They were holding hands and hugging each other.
Funny thing is that she knew I was on a school trip there.
She was either too dumb or she just didn’t care.
She went pale, and flew away.
Days later met her to give her all her stuff and she tried to blame me.

I looked down when I put down my stuff and there it was.
It was the third time.’
I glanced at the date and it was two weeks prior.
I said, ‘So youre sleeping with X huh?’
She said, ‘What?
I said, ‘Well you wrote it right here that you did.
“She swore she didnt do it on purpose; but she did.
Thats the throw in of person she was.
Everything was like that, always trying to frame things like I was the bad guy.
That was her playbook and it took me way longer than I should have to figure that out.
I was just like ‘Whatever.

I didn’t suspect a thing.
His exact words were: ‘I met someone.
You’re my best friend, and I love you so much, and I hate myself for it…
I just had to come clean.’
And soon after that, he explained that he met her on Match.com.
(Raises even more questions, I know.)
And that they’d been on a few dates.
(Yes, I went.
