Intro
(Cheated on again. How many does that make now?)
I sink into sadness while staring at the messages from the boyfriend I just dumped—no, my 'ex-boyfriend'.
A few hours ago, I caught him in the classroom after school, embracing and kissing another girl. I dumped him on the spot, and even though I listened to his excuses over text, they all felt hollow, so I blocked him. Even though I've unlocked the shameful achievement of 'Blocking 3+ Cheating Boyfriends,' I don't get a title or a trophy like in a game.
(I thought being controlling would backfire, so I gave him space... maybe that was the problem. ...No, it doesn't matter anymore.)
Men who cheat are trash, and women who go after people in relationships are trash too. I can't trust anyone anymore. In the end, everyone is the same.
When I reach a conclusion, the answer is incredibly simple. Everyone is the same. No one can be trusted.
I won't let anyone into my heart ever again.
Today, another day of not wanting to trust anyone has begun.
I head to school while listening to my favorite song through my earphones.
It wouldn't hurt to take today off, right? I call the school to report my absence.
To try and lift my mood even a little, I stop by a convenience store on the way to school.
