Confusion

He sat up in the bed, slowly turning to the side and placing his feet on the floor. He was doing his utmost to be quiet. He didn't want to wake her up. He turned to look at her sleeping form beside him. She wouldn't wake if he was careful. He had made sure she was worn out. Good sex does that to a woman. He knew that.
The moonlight came in softly through the window, accentuating her curves. It gave relief to the peaks and valleys on the sheet, making her seem more voluptuous than she really was. He felt a slight twinge of sadness for her. He knew she really liked him, but he couldn't say the same. Sex had just been a means of relief, one he needed. But that was all he wanted.
He wished he could feel something more than sexual attraction for someone other than his goddess. But She had taken his heart, and there was no room for anyone else. His flesh still had needs, so he allowed himself dalliances such as this one. But they always ended badly. No one ever believed him when he said that he just wanted to have fun.
Slowly, he pulled his pants up his legs. Just halfway though, so he could tie his shoes. This wasn't his first time, he had learned his lessons well. The first thing to put on was always the shoes. You never knew when you had to run. Shoes tied, he pulled up his pants, inch by inch, standing in the process. He was almost home free. Just a few more articles of clothing and then he was out.
She moaned in her sleep and rolled towards where he should be slumbering. A crucial moment has arisen. If she didn't feel him laying beside her, she might wake and catch him half gone. This would be bad. Quickly thinking on his feet, he moved a pillow into the place where he should be laying. Not a moment too soon, as her hand came in contact with the pillow and she just snuggled into the covers deeper.
Whew, he breathed a sigh of relief. He had his shoes on, he would have ran, but better not to be faced with that decision. Slowly bending down, he picked up his shirt and pulled it on. Usually this sort of thing wouldn't matter. He normally tried to find the type of woman that didn't care if you fucked and fled, but sometimes plans go awry. Fully dressed, he looked down at her face. She wasn't ugly, but she wasn't the one he loved. However, she could suck a dick.
Knowing if he hesitated any longer, he would be fucking her again, he left. He left knowing she would be hurt and angry. He left knowing she would carry a grudge and do her best to ruin him. He left. Because she wasn't the one he desired.
