I never pegged myself to be a cheater. It just happened. It just happened to happen with my best friend's fiancé. I know, how low can I get right?

My best friend and I have been through almost everything. We grew up together, went to Hogwarts together, had our first boyfriends together, but never this. I don't plan on telling her either, well not at this exact moment. I've always been jealous of Ariana, with her perfect brown hair and her vivid turquoise eyes. She was around 5' 7," the perfect height. Not too tall, or too short. She grew up in this life, she was a pureblood, not a muggleborn like myself. She grew up with the best of everything and always got what she wanted. I grew up in a regular muggle neighbourhood in Surrey. I had a plain name, Lily Marie Evans, while she had such an exotic name of Ariana Ursa Grey.

My parents always told me that I was a mistake, I mean who wants a kid like me? With scarlet red hair and jade green eyes, I was definitely one in a million. It also didn't help that I was a staggering 5' 11". My parents wanted acceptance and I generally didn't help. I've always been different. Ariana always seemed to be tanned, while I was stuck in a milky white complexion. Ariana's skin was so clear, while mine was speckled with freckles. Ariana had a fabulous PR job for a wizarding record company. I on the other hand had an un-fabulous job in the Department of Law Enforcement. I always thought that it was what I wanted, but I was wrong. I suppose the only good thing that came out of it was James Potter. James Potter was the epitome of perfection and I immediately knew that nothing would happen. We became great friends, meeting for drinks and meals, but deep down I was kidding myself.

I prayed that something would happen, I mean I really cared for him. After about six weeks of training together I decided to give up. Nothing was going to come out of it, I mean who wants to date, let alone marry a fiery redhead. That's right, no one. Instead, I decided to set James up with Ariana. It started with one date, then two, and the next thing you knew they were on the cover of the Daily Prophet. "Best Looking Couple," they claimed. Everyone could see it, I mean their genes were beyond fantastic. After the paper incident, I noticed something different in Ariana. Her turquoise eyes seemed to sparkle with love. She came to me and told me. She told me that she was in love with James Potter, my James Potter.

I think at that exact moment I knew my chances were gone. Before, I was making mountains out of anthills. I was secretly hoping that he would dump her and proclaim his feelings for me. That never happened, because a week later James proposed. They were getting married, as in together forever. When Ariana displayed her fabulous SIX carat ring, I was overjoyed for her. As children we always dreamed about our weddings, the dress, the cake, and most of all the man. Ariana had it all while I was green with envy.

I never knew how much control I really had over Ariana until the dress fitting came. As the legend has it, when the bride-to-be tries on the right dress, she will know immediately. We had been to over 4 stores, tried on over 100 dresses, and still no dress. When we entered the fifth store, she tried on a dress and I decided to test my luck. She looked good, but she had looked better before.

"Oh, Ariana. That's the dress!" I proclaimed.

"Are..Are you sure?" She questioned. I could see the uncertainty in her eyes.

"James will simply fall over when he sees you." I cooed.

Ariana then decided to leave the uncertainty behind, after all, I was her best friend. She purchased the dress three minutes later and we were out the door.

Three days later, it was my twenty-second birthday. Ariana decided to throw a huge party at the Leaky Cauldron and invited everyone including her beloved.

About two hours into the party, Ariana was completely smashed. James made Remus take her home after she started to dance on the bar.

An hour later and three drinks later, James and I were talking. Soon the talking became in-dept conversations. After a few more drinks, we were both pretty buzzed but by no means drunk. It was one in the morning and James, being the gentleman he was decided to take me home. He called a taxi and we set off for my apartment. He walked me up the three flights of stairs, and being the polite girl I am, I invited him in. Okay, big mistake. We had a couple more drinks, and soon enough the alcohol had taken a toll on our bodies. We were getting a little too friendly, I mean the man is getting married!

I turned around, and his lips were on mine. Merlin, those soft lips that I had been dreaming about. I immediately responded, soon enough his tongue was begging for entrance. I obliged, merlin he was a good kisser. Our kisses became more frantic, along with some more intimate touching. One after another, our clothes landed on the floor. Soon enough he was on top of me, about to make us one. He leaned into my neck and whispered "Are you drunk?" I replied with a shake of my head, "No." He smirked, "Good, because I want you to remember this." We were soon as one, my back arching against his touch. I had never felt so alive, we seemed to fit together like puzzle pieces. After we "made love" as he called it (which only made it feel so much better), we both fell asleep.

Hours later I awoke to James by my side. Something was beeping, I slowly crawled out of bed to my cellphone. Merlin, thrity-nine missed calls, from Ariana.

"JAMES" I screamed.

"Huh..uhh…wooah..what," he was only waking up.

"Ariana called thrity-nine times!"

To this, he seemed to wake right up.

"Shit! Shit! Shit!"

"We need to think of a plan Lily. I'm going to tell her that I spent the night at Sirius', he'll cover me. If she asks, just tell her that you didn't see me after the party..okay?"

I was on the verge of crying, the guilt seemed to rush through my veins.

"Lily, don't cry. It'll be okay."

He walked toward me for a hug, which I couldn't accept.

He left shortly after, no more words were shared.

I knew deep down that this was only the beginning.
