The Only Color that Mattered (as read in a British accent)

I didn’t know what colors were
Until that moment I met you.
Taking my hand you showed me
How the green trees could swim

Through the blue waters of the sky.
How the orange light can shimmer off
The bronze puddles in the backyard.
How the night’s black air could turn
Into a grey dawn of blissful serenity.
But then you decided cheat on me.
So now the only color I can see
Is the brown shit I left on the hood of your car.

There are many definitions of cheating. To be a cheater you don't always have to physically cheat. Cheating on a loved one can also be defined as privately talking, texting, or seeing another person behind your significant others back. If you have to hide messages or people from your loved one you are cheating. Cheating can also be defined as sexual contact. To be a cheater remember it doesn't always involve sexual contact.
I found messages of my boyfriend/girlfriends phone with another girl. They were flirty and descriptive messages. He/she was a cheater

I walked in on my boyfriend/girlfriend kissing another girl/boy. My loved one was a cheater he kissed another girl/boy.
