Dream of girlfriend, having sex

I had my own house, my best friend and his girlfriend just got back from a vacation they were going on for their one year anniversary. I go to hang out with my best friend, but he's not there. Instead his girlfriend is and she is coming on to me really strong, we end up having sex in the shower. In the middle of it she says "I love you" and I look at her, and say "I once loved you, but now I hate you" and I left immediately and headed back home where my best friend was waiting for me with tequila and cotton candy
