Just Met Someone New and It's Intense

So I just met this girl last night. We're both in our twenties, at the gym after my shift ended early today. She was there for a PT session with another trainer, but we clicked. After her session, she suggested we go back to her place. Now here I am, questioning why I gave up on my previous relationship just weeks ago only to dive headfirst into this one-night stand scenario. It feels like it’s all too fast and yet, there's a chemistry that's undeniable. We spent the rest of the night exploring each other in ways that were both thrillingly new and oddly comforting. I'm torn between appreciating the freedom and second-guessing if this is just a rebound from my breakup. Maybe I’m really over her and ready for something new, or maybe I’m confusing physical attraction with emotional attachment. Who knew my decision-making skills could go out the window because of one session at the gym? It's all so... overwhelming right now.
