When My Client Crossed the Line During a Session

So yeah, I've been married to my wife for five years now. We have two kids, and she's usually pretty understanding of me taking on clients outside our home gym. But lately, this one client has been driving me nuts. Let’s just call her Jane. She's in her early thirties, super fit, we're talking about someone who can keep up with me during a session, which is no small feat. Now, I've always made sure to keep everything professional between us. That's my rule; it's just how I roll. But last week... things got weird. We were doing some floor work, you know the moves, and there was this moment when we were both on the mat, working through a stretch that involved me pressing her legs together and pulling them towards her head. She was really pushing herself. And then it happened. She made this soft noise, like she was surprised by something in her body responding to the pressure I had on her thighs. It took me back; it wasn't what you call a normal thing during a workout. And it wasn’t just that sound, there was an intensity and a closeness between us that felt different. So we finished up, but the next day she sent me a text saying how much she enjoyed the session and how I had this way of making her feel something... special. My gut told me to stay away from it, keep things professional. But you know, there was this small part of my brain that kept thinking about that moment on the floor. It’s not like we acted on anything. We're both adults here; I didn't try to take advantage or anything like that. That would be crossing a major boundary in more ways than one. But why did it feel so... charged? Like there was something deeper going on, and I'm just trying to understand where all of this is coming from. So now what? Should I keep things exactly as they are and pretend this weird moment never happened? Or should I explore it somehow within a safe space that respects everyone’s boundaries? It's been nagging at me since the day it happened, and honestly, writing this out helps clear my head.
