terrible dreams

I met up with Dudley on a ride similar to a cross between "It's A Small World" and "Splash Mountain." He was waiting off to the side for Alisa but I happened to convince him to do down the water flume and talk to me. We got down to the bottom, me first, then him. Then we decided to talk later.
The next day, I had to work with Alisa for a little bit and I dished out a couple catty comments to her in the office. She reacted like she normally did with her annoying laugh. Then I walked by the produce section where she was talking to Linda and a couple of other crewmembers about her "times" with Dudley and what their future plans were. I walked by like I hadn't listened in on the conversation but was secretly eavesdropping. It was obvious that I was idling by and I think they knew to but decided to keep their voices down anyway.
Back at the same park from the day before, I saw a rumpled up maroon blanket. I had replayed the events in my mind- I saw them rolling around by a pool outside. He was on top of her and was kissing her neck. She looked like she was in heaven. That's when I realized the rumpled blanket meant they had fucked again. At this point, they were trying to develop a serious relationship, even though he was still leaving for the military in a couple of weeks.
Why her? Why make her the last "fling"/relationship he has before he leaves and not let his relationship with me be the be all and end all of his relationships before going to the Air Force?
I think this dream makes me realize...I can't talk to him again, at least, not for a long time.
I might have dreampt all this because I called Alisa yesterday but she was working. Dudley never called me like he said he would.
I hate them both.
