Blair felt as if her whole word were collapsing in on itself. The only thing she had been sure of in her entire life was the fact that she was meant to be with Nathaniel Archibald. She had been planning their wedding since the first grade. He was the only boy she had ever loved and being the fool she now realized she had been she had thought she was the only girl he had eyes for. She should have known there was something between her boyfriend and best friend. Serena was the pretty one who always got everything she wanted. She was the princess of the story while Blair had always been the ugly step sister. Blair was the good girl who never got in to trouble and Serena was always in trouble. Serena also had the ability to have any man at the drop of a hat. The brunette should have known it would only be a matter of time until Nate became one of her victims.

"I knew it! I always knew there was something between the two of you!" She raised her dainty fists to pound at his chest. Tears were cascading down her cheeks. "Is that why you were so distant when she left? Is that why you won't be with me because I never compare to the perfect Serena Van Der Woodsen?"

"Blair…" The blond haired boy tried to touch his girlfriend's cheek in order to calm her down, but she slapped his hand away acting almost as if his touch burned her.

Not wanting to hear his confession of love about her once best friend Blair set her hands on his chest and pushed him towards the door. "Get out right now! I hate you and I hate her! Go back home and dream of your perfect girl because obviously I was never enough for you. Get out! I never want to see you again Nate Archibald!"

As soon as he left she allowed herself to fall to the floor as she came undone. Sobs got stuck in her throat as her body shook from the shock of the revelation. The last time she could remember letting her-self come undone in such a way was when her father left to be with his male lover Roman. Usually Blair forced herself to be calm and collected, but there were times like this when she could not get ahold of her emotions. Times when her world felt as if it were over for good and right now her whole world and the perfect kingdom she lived in had shattered in to a million different pieces.

In the past she knew exactly how she would handle the situation and get her world to stop spinning, yet she had a made a promise to both Nate and Serena she would never fall back in to bulimia. Then again Serena had promised to always be there and Nate had sworn to love her forever so if they could break their promises to her why shouldn't she be allowed to do the same thing? It would only this one time anyways to help her deal with the stress of everything going on around her. She rationalized her choice by telling herself that it would be good for her. It would make her feel better and nobody ever had to know.

Getting back to her feet she quietly made her way downstairs even though her mother was gone and Dorota was nowhere to be seen. It was years of practice coming in to play. She had always been good at never getting caught. Finally Blair made it to the kitchen and she opened the pantries looking for something to eat. She found a box of graham crackers and a bag of marshmallows. Grabbing the items along with two left over muffins from breakfast she made her way back to her room shutting and locking the door again out of habit.

Wiping the dried tears from her cheeks she started in on the graham crackers. She broke the first one and stuffed it in to her mouth. As she chewed and began in on the second half she couldn't help, but picture different times she had shared with Nate. She remembered their first kiss when he had gotten ready to leave after studying at her place for an upcoming math test. She remembered their first official date as a couple and how proud she had felt entering school with his arm and hers locked together. Next she recalled all the times they would talk about the future together and how they would both attend Yale before getting married. It had all been planned out perfectly. As she continued to eat everything in sight and remember long lost times she started to feel angry. Her life had been perfect until Serena had come back and ruined it all. All her once happy memories with Nate were forever scarred by the knowledge he had slept with her best friend. It made Blair question every moment they had ever shared together while she analyzed them in her mind trying to pick out things she may have missed.

Eventually her supply of food was gone and she got up to go to her bathroom. She turned on the water facet before falling to her knees she stuck two fingers down her throat. Her body jerked forward as her gag reflex kicked in. It had been a very long time since she had done this and it hurt a whole lot more than she remember, but she figured it was because she was out of practice. It took a couple more tries before anything actually came up. She could feel all the recently eaten food along with stomach acid make its way back up her throat and out of her mouth before falling in to the toilet bowl. She continued doing this for a few minutes before finishing and flushing the evidence of what she had just done. Standing up she wiped her mouth with the back of her hand before washing her hands and then cleaning her mouth with mouthwash.

Feeling better Blair sighed and went to her room to clean up the wrappers and empty boxes. When she had completed that task she went to sit on her bed and suddenly all the pain came rushing back. Her heart felt like it was cracking before slowly exploding in her chest. She knew that she needed to get rid of this feeling and only knew of one way to get it done. She would have to binge and purge again, but she did not want to risk eating any more food in case when her mother came home she noticed something. So she would call the one person who wouldn't ask a million questions. She called the only friend she had left that was not an annoying minion. She pulled out her cell phone to call the one and only Chuck Bass.

TBC…

AN: So this is my first original Chuck and Blair fanfiction. I am nervous about writing it, but I think the start came out alright. In the next chapter you will get to see some of Chuck. From this point on the chapters should be at least two thousand words and no less. The only reason this chapter was so short is because it is just the introduction. I hope that you all liked it and I put a preview at the end of this for you all so you can get an idea of what to expect in the next chapter.

Please R&R like always!
