What does it mean when you have a dream about your boyfriend cheating on you?

So, I was just taking a nap and I had a dream about my boyfriend that I've been going out with for two weeks and a few days now, cheating on me. This was the dream: It was after school and my dad had just came to pick me up so, I was in the car and right before he drove off I told him to stop for a second because I had seen my boyfriend carrying some other girl (I didn't tell my dad that I saw that happening, i just told him to sop) and my boyfriend and the girl (he went out with her last year and they stayed friends but she told me she hated him now because she thinks he's "fake") were laughing together while he was carrying her and I was pretty confused because she told me she hated him and then I see them making out. So, I got out of the car and yelled, "DAVID!" and I walked over to him and asked, "What the **** was that?!?!" and he tried to hug me and he sort read the look on my face I guess because he said, "We're done!" right before I could. Well, we sort of said it at the same time. The reason I'm tripping so much because of this is because David is sort of a player. So, I'm wondering is this dream is a sign that he's hooking up with other girls. HELP!
