Dream: My Girl and Nat

I only remember one part of this dream. I don't remember where we were but all the people that usually go to Chad's house after church were there. Nat was lying down against a wall and everyone else was around him talking. Then the girl I like lays down on top of Nat. I was kinda upset but I was controlling myself. We talked for a while and I was doing my best to ignore Nat and the girl. The girl and I made contact every now and then and she seemed to be enjoying my pain. Then she started carressing Nat's face and I think she started to kiss him. I couldn't contain my aggravation after that. I started fidgeting and looking anywhere but towards her and Nat. I was talking irregularly too. The whole time I was trying to think up an excuse to leave. I eventually did leave and I could tell that she was enjoying this. While away I calmed myself down and then came back. We talked again for a while and I made eye contact with her for a while and she knew then that it was nolonger affecting me and she looked very disapointed. Then she turned over and started hugging up on him and I think they started making out. After that I didn't look away or anything, I just felt the deepest feeling of hopelessness and despair. That's all I remember of that dream.
