Dream About Passionate Sex Rejection Relationship

I dreamed I went to a major city on an airplane with a group of my friends and an ex-crush of mine Who in real life I know as a cheater. I had an entire adventure with them and eventually came back the same day on an airplane. I started growing closer to my crush and eventually we ended up having passionate sex, so intense that I worried about the morning after pill afterwards, I also forgot that we were doing it on my friends sheets and that sex leaves a residue so I had to apologize for that, I then tried to admit my fetishes to my now girlfriend people kept interrupting me and eventually when I did reveal my fetishes she flatly rejected them which completely stunned me and I ended the dream contemplating the relationship.
