My Former Student's Seduction After The Breakup

I was just getting over a long-term relationship when I met him. He was one of my students, older than most undergrads by a few years, he’s forty-two. We both knew the rules and that our age difference was huge, but there was something about his maturity, how we could talk like peers... He sought me out after class one day, said he’d always admired me from afar, but now felt closer. The breakup left me vulnerable, and I found myself intrigued by him. We started meeting at a coffee shop near the university to chat more freely than in public lecture halls. It felt illicit yet exciting, knowing we were breaching boundaries set up for our safety and comfort. One night after several weeks of these meetings, we ended up alone in my office after hours. I was leaning on him for support as I tried to wrap my head around everything, and he kissed me softly, his beard rough against my face. We moved slowly but inevitably toward the couch behind us. I’d never been with someone so different from past partners or exes; there were no shared expectations of normality here, just an exploration of something new and exciting. He was gentle but insistent, his hands exploring me as if discovering the map for the first time. His mouth tasted different too, no lingering traces of anyone else’s body. We spent hours together that night, and I can’t deny it felt freeing to be with someone without a shared history weighing us down. But guilt hit hard after; we both agreed it was never meant to continue beyond a momentary lapse in judgment. Despite the illicit nature of it all, I found myself wanting more, is this just residual chemistry from my breakup? Or am I drawn to him specifically because of our forbidden status? I'm confused and worried now about what might happen next. Have other people had similar experiences that didn’t end up badly? Is it normal to feel such strong attraction even for a short time after an unhealthy relationship ends?
