I had a dream I was madly in love with my fiances best friend?

Haha I had a really stange dream the other night and wondered what others thought it could mean. There was one part of my dream where I had a fiance (i dont in real life) and I absolutely hated him. He was mean and aggressive and bossy! He was introducing me to his family and friends and then he opened a door and sitting on the floor was an ugly guy who looked like david bowie. I fell in love the moment I saw him! And didn't want to leave his sight and wished i was marrying him instead. My fiance said "this is my best friend." and then I went to the bathroom and my fiance came in and starting making a p at me and I pushed him away and said "gross!! stay away from me" and he got very angry and stormed out of the bathroom. I sat in the bathroom crying and his best friend came in and comforted me and I revealed my feelings towards him. He told me I had to go back to my fiance and got me to stop crying. I told him that I only wanted to be with him and he hugged me and then walked out of the bathroom and that was the last I saw of him!! What do you think this dream could mean, if it means anything at all lol.
