Hey guys, I'm back with another story. I know I said the same thing over a year ago and I'm sorry. This is something that I thought of after watching the movie City Of Bones and the TV show Shadowhunters. It's my first TMI story, so I hope you'll like it :)

Clary's POV

I can't believe it. How could he? I ran away from him. From that place where I saw him kissing some random blonde girl. How could he do this to me? I thought he loved me. Flashbacks of him and her, pressed against each other kept flashing through my mind. I wanted to run even faster, but I couldn't see because of my tears. I slowed down and headed to a nearby forest. It calmed me down. Also, I needed to sort out a few things. What do I do? I didn't feel like going to the Institute. And I definitely didn't feel like talking to anybody. Thinking about how I would get tormented with questions from everyone, I decided to not go back just yet.

I burst into crying again. I tried to hold onto the closest tree, but that didn't stop me from sinking to the ground. I thought about all the times that we couldn't be together. How we had to fight for our love. But I guess it meant nothing to him. All the times he told me he loved me... it was all a lie. One big lie. Oh gosh, I wish I wasn't so stupid. Everyone warned me. Everyone told me that I shouldn't get close to him and date him. He will break your heart, Clary . I remembered what my mom told me. Simon and Luke kept telling me the same thing, but I ignored them. I ignored all the red flags and warning signs... I should have known.

It was getting dark quite fast, so I thought it would be a good idea to go back. I got up from the dirty ground and started making my way through the forest. It wasn't completely dark and I could still see pretty well. By the time I got out of the forest, it was dark, all the street light were lit up and there weren't as many people out as before. When I spotted the Institute from afar, I got nervous. When if he's there? I knew I wouldn't be able to act like everything was okay, like I didn't see what I saw a few hours ago.

I was afraid to open the door. Or even knock. I just couldn't bring myself to do it. After a few moments of staring at the door, I turned around. I sat on the cold hard ground and started crying. Again. Third time that day. I didn't want to face him. I didn't want to have anything to do with him ever again. But I had to go there. Maybe I could find Izzy, she would help me. So I picked myself up from the ground and slowly opened the door. The Institute was dark, but that was understandable, it was really late. I got to the kitchen and poured myself a glass of water. All that crying dehydrated me. Then I put the angry glass down and headed to my bedroom. But I felt myself collide with something big and hard. Someone.

"Clary?" Oh no no no. Please, anyone else, but not Jace. "Clary, where have you been? We've all been worried sick about you." I didn't respond, I could imagine how "worried" he was. I just brushed past him, ignoring what he was saying.

"Clary, stop! Talk to me!" He grabbed my wrist and pulled me back to him. I couldn't bare it anymore.

"STAY AWAY FROM ME! I DON'T EVER WANT TO SEE YOU AGAIN!" I didn't mean to shout, I'm sure I just woke up the whole Institute. Jace just looked at me, obviously he was at loss of words. I freed myself from his grip and took off running to my bedroom. I ran up the stairs but then I bumped into Isabelle.

"Clary?! What was that shout? What happened? Are you okay?" Afraid of breaking down again, I just hugged her. She immediately hugged me back, without saying anything.

"Wanna go to my room and tell me what happened?" She said softly and let go of me. I nodded and followed her lead. I knew that I could trust Isabelle with anything and she would understand. She closed the door behind me and we both sat on her king-sized bed. I explained what happened. Everything, from beginning to end. Tears were running down my face by the time I finished.

"Oh Clary...I'm so sorry." She gave me another hug, this one lasted much longer. I smiled slightly, thanking God for Isabelle.

"Do you want me to walk you to your room?" I just nodded and got up from her bed. Luckily, we didn't meet Jace on the short way to my room. I don't think I would be able to handle it.

"Thank you so much, Izzy." I said putting my hand on the door knob, ready to open the door.

"Remember, Clary. Anytime you need me, I'm here for you. Sleep tight." I gave her one last smile before opening to door and going in. I closed the door behind me and turned on the lights. I turned around, but what I saw nearly gave me a heart attack. It was Jace, he was sitting on my bed. But... he was all beaten up, he had a black eye and his lower lip was bleeding. But he didn't seem to care. I wanted to feel sorry for him and... No! I took a deep breath.

"What do you want?" I asked him bitterly. He stood up and started walking to me slowly.

"Clary, I just want to explain myself. Please..."

"What do you want to explain about the fact that I saw you kissing some random blonde chick? It sounds pretty clear to me." I ran my hands through my hair. This whole situation. God... It was making me feel like I'm going to lose my mind any moment.

"I swear that it meant nothing to me. I only love you and I will always love you. Please, forgive me. I don't know what I would do without you." I looked into his golden eyes. They lacked the bright spark that always used to be there. They were dark. And they looked like they were filled with hopelessness and emptiness. And he was... He was crying. I'd never seen him cry before. It almost made me want to take him back. Almost.

"What's done is done. Please leave." He nodded and slowly started walking to the door. As I watched him, I couldn't move. All the good memories of us flashed through my mind. I never thought that he would throw it all away like that. So easily. Like a crumpled piece of paper. Before opening the door, he turned back to me.

"Clary... I just want you to remember that I will always love you. You're the only person I've ever loved and I lost you because of one stupid and reckless mistake, which I'm going to regret for the rest of my life. But if one day... if one day something makes you change your mind and you'll decide to forgive me. I'll be here." With that he left. I couldn't believe it. I just stood there and stared at the door. God knows how long I've been standing there, I lost track of time. Then I broke down again. He was gone. Everything we ever were was gone. I felt like everything I've ever known disappeared in the blink of an eye. I couldn't take it. I have to get away from here. I got up from the ground and headed straight to my closet. Do I really want to do this? I didn't stop. I opened the closet door and looked for a backpack. I found one that was large and black. Perfect. I threw it carelessly on my bed and started filling it with clothes. Not all of them. Just enough to last me a couple days. Next some toiletries. What am I missing? I noticed my sketchbook lying on the bedside table. I put it in the backpack. I put in some other important stuff and zipped it up. I grabbed my phone that was on my pillow. Take it or leave it? I decided to take it, making a mental note to not pick up any phone calls or answer messages. I slowly opened the door and looked around. No one was in the hallway. It was probably 1 AM so it was understandable that everyone was asleep in their rooms. I closed the door as quietly as I could and headed towards the staircase. I swiftly walked down the stairs and made my way to the front door. After taking one last look around the Institute, I left the building and stepped into dark, cold night.

I hope you liked the first part :) At first I wanted it to be a one-shot but it was getting too long, so I had to separate it. Review and tell me what you liked or didn't like about the first part :)
