Dreams get me thinking..

So theirs this girl... And obviously I like her.  I dream about her. I don't even dream about my own  boyfriend. So yeah this is serious. So I had a dream that I cheated on my boyfriend with her. But this is a dream right so why am I so worried about this? May be its because she's fucking hott and i really want to be with a girl like her. But really what I'm really afraid of is messing up a good thing which is my boyfriend. So I just can not let that dream come true even though I do want to get with her.
