...A One-Night Betrayal...

I'm an artist in my mid-twenties and have been with someone for over a year. We share many interests but our sexual boundaries differ, particularly when it comes to roleplay scenarios I enjoy. Last week, at an art event, I met this stunning woman who understood my fantasy perfectly, a dominant figure willing to take control. It was exhilarating yet terrifying... knowing how much I valued my partner's trust. What drives me to seek out these intense connections outside a relationship? Am I just looking for validation or something more sinister? Thoughts and advice appreciated.
