Defiance in the Classroom

I recently separated from my high school teaching partner of twelve years. I didn't see it coming until she suddenly wasn't there anymore, leaving me alone with my thoughts and a newfound sense of freedom. One night, after too much wine and not enough sleep, I found myself drawn to a student, someone who isn’t a child but has that vibrant energy only the young possess. We ended up crossing lines no one should ever cross. It felt like liberation at first, but now it's complicated by guilt and fear of consequences. Is this something others have experienced too? What advice do you have for dealing with these overwhelming feelings?
