Poison- Simon

You loved Simon with all your heart, you really did.

You were blinded with love, so in love that you didn't even realize how he was slowly falling out of love with you, or perhaps didn't even love you enough to begin with.

You woke up, and stretched your arms out, smiling as you felt your limbs pop.

"Morning" you mumbled as you turned towards Simon's side of the bed, only to realize that it was empty.

You grabbed the sheets to cover your body and sat up in bed, looking around only to see no trace of him.

You got out of bed and wrapped your robe around yourself as you walked out into the living area of the flat.

You spotted a sticky note on the fridge and walked over to it.

You sighed as you read the note.

Every single time Clary needed him he would run to her like a lost puppy so you weren't even surprised when he had written in his messy handwriting that Clary had needed him at the institute.

You walked back into the bedroom to grab your clothes and a towel before jumping into the shower.

.....

You walked in through the doors leading into the institute at around 8am, and to no surprise the place was already buzzing with activity.

You spotted Jace and walked up to him.

"What's on the agenda today?" You asked.

Jace looked up from the iPad in his hand.

"Forsaken, can you go get Clary and I'll let Izzy and Alec know. Meet back at the armory?"

You nodded your head. "Where is she?"

"Should still be in her room" Jace said before he headed off in the opposite direction.

You began to walk towards Clary's room a bit confused, why would she need Simon if she was still in bed?

You could feel doubt creeping up in your veins, but you quickly pushed it away.

No, Simon would never do that to you.

But you couldn't help the chill that creeped up your spine when you reached Clary's room and reached out to knock, but quickly decided against it and opened the door instead.

Your hand dropped to your side when you took in the sight in front of you.

Simon immediately scrambled off the bed, and stood staring at you in horror in just his boxers.

You looked over at Clary who pulled the sheets up to cover her naked body.

You huffed before you turned on your heel. "Jace needs is for a mission"

You quickly left the room and hurried down the corridor, only to hear the sound of someone chasing after you.

"[Y/N], stop!"

You stopped abruptly and saw Simon come running towards you, jeans now on and him pulling a t-shirt down over his chest.

"What, what could you possible have to say to me. I think your actions said everything I need to know" you barked out at him, feeling rage bubbling up in your veins.

Simon stood chestfallen, as if he didn't know what to say.

"And to think I loved you, you're nothing but poison. I clearly picked me poison, just didn't realize it was you" you spat before you turned on your heel and rushed down the hall, biting back the tears that were welling up in your eyes.

How could you have been so blindsided.

A/N
I can honestly never understand why people cheat, like if you're unhappy in your current relationship why not just leave before you get involved with someone else, it's so selfish.
