Unfaithful

I was supposed to post this weeks ago but certain things kept getting in the way. This is the last chapter.

Parts of the song used might be altered to make it fit the story. The title of the story is actually the name of the first song used. Lyrics of song will be in italics.

I don't own Cruel Intentions or the lyrics of the song 'Say Goodbye'. Say Goodbye was performed by Chris Brown.

Chapter 3: Say Goodbye

He had put it off for long enough, he needed to tell how he felt before things get worse. He couldn't even remember what he loved about her in the first place. It probably had something to do with the fact that she had been different from all his other conquest. Though now he wasn't exactly sure what it was that made her different. All he knew now was that he couldn't keep pretending that their relationship was okay, it hadn't been okay even before Kathryn had come on the scene. They had just been lying to themselves, the way they still lying to themselves. At this rate, they were going to end up hating each other. She was about to go to one of the various charities she seemed to love so much but he could never bring himself to care about. Now would be the best time for him to tell her before he lost the nerve to do it.

"Look we have to talk" he said, stopping her from leaving.

"I have to get to retirement home. They are expecting me" she said.

"I know. It's just... some things I have to get of my chest, alright?" he said. Leading her to a chair he said, "Baby come here and sit down, let's talk."

She sat than feeling a bit worried about whatever could be so important that he would require her to sit before he could tell her about it.

"I got a lot to say so I guess I'll start by saying that I love you but you know this thing hasn't been a walk in the park for us. I swear it'll only take a minute. You'll understand when I finish.And I don't want to see you cry but I don't want to be the one to tell you a lie" he said, still standing.

"What are you trying to tell me?" she said as she began to panic. She didn't like the way the conversation was going. She had a distinct feeling he was about to break up with her.

How do you let it go? When you just don't know what's on the other side of the door when you're walking out? Talk about it. Sebastian thought to himself. "Everything I tried to remember to say just went out my head. So I'm going to do the best I can to get you to understand 'cause I know there's never a right time to say goodbye but I have to make the first move 'cause if I don't you going to start hating me. Cause I really don't feel the way I once felt about you. Girl it's not you, it's me I kind of have to figure out what I need" he said.

"Are you're breaking up with me? You can't do this to me now." she said, her eyes beginning to fill with unshed tears.

"There's never a right time to say goodbye but we know that we have to go our separate ways and I know it's hard but I have to do it and it's killing me cause there's never a right time right time to say goodbye" he said.

"You're breaking up with me" she said as she began to cry.

"Girl I know your heart is breaking and a thousand times I found myself asking, 'Why? Why?' 'Why am I taking so long to say this?' But trust me, girl I never meant to crush your world and I never thought I would see the day we grew apart" he said, trying to get her to see that he had never meant for this to happen but they didn't belong together. "And I want to know how do you let it go? When you, you just don't know? What's on the other side of the door when you're walking out, talk about it. Girl I hope you understand what I'm trying to say. We just can't go on, pretending that we get along. Girl, how you not going to see it?"

"You don't mean it. Was it something I did?" she said. A voice at the back of her head telling her that he had found out about the affair and was breaking up with her because of that.

"There's never a right time to say goodbye but I have to make the first move 'cause if I don't you going to start hating me cause I really don't feel the way I once felt about you. Girl it's not you it's me. I kind of have to figure out what I need. We know that we have to go our separate ways and I know it's hard but I have to do it, and it's killing me cause there's never a right time right time to say goodbye" he said.

She looked down and shook her head. "I just can't accept that. We just need more time to adapt how differences" she said.

"Listen to your heart. Girl you know, we should be apart, baby, I… I just can't do it and sometimes it makes me want to cry" he said as he bent down and held her hand, trying to get her to understand that this was the best thing they could do. "There's never a right time to say goodbye but I have to make the first move 'cause if I don't you going to start hating me cause I really don't feel the way I once felt about you. Girl it's not you it's me. I kind of have to figure out what I need. We know that we have to go our separate ways and I know it's hard but I have to do it, and it's killing me cause there's never a right time right time to say goodbye" he said. This time she nodded.

After Sebastian broke up with Annette, he convinced Kathryn to come over to his house with the help of Blaine as Kathryn wasn't talking to him. Kathryn was convinced he had broken up with Annette after she came to the house and saw that there was nothing to show the presence of the other girl. They started making but were interrupted by the arrival of Annette who forgot something in the house. She recognized Kathryn from her therapist's office. Annette unwittingly let it slip that she cheated on Sebastian because she believed that Kathryn told him. Sebastian got angry but Kathryn calmed him down by reminding him that he did the same thing. It turned out that Kathryn suspected Annette might be Sebastian's girlfriend but wasn't sure. Sebastian decided that it didn't matter any more since he and Annette were no longer together. Annette took what she came for and left the house.

"Sebastian" said Kathryn.

"Yes" he replied.

"If you ever cheat on me, I'll make you wish you never laid eyes on me" said Kathryn. Sebastian simply smiled and went back to doing what he was trying to do before they were interrupted.

This last chapter doesn't feel as good as the previous ones to me but I hope readers still like it.

This story is actually dedicated to Kerimack's fanfic 'Turn Around'. It's the only fanfic I've read in which Sebastian met Annette before Kathryn. She cheated on him in that one as well. It is also dedicated to Salvaveritate for her one wonderful three chapter fanfics.

The story itself was inspired by listening to Unfaithful, Lie about Us and Say Goodbye in exactly that order. Hope whoever reads this likes it enough to review. I need the reviews to decide whether to go through with an idea for a full length musical fanfic I've been thinking of writing called The Machiavellian Prince and The Ice Princess.

It features how Kathryn and Sebastian met, part of the movie and a sequel to the movie.
