when i went too far last week

i met her like five years ago at a kink event and we clicked pretty hard right away. she was into all sorts of stuff and i had always been a little more vanilla but i found myself wanting to try everything with her. we started slow but over time, our dynamic shifted and she really took on the submissive role in most scenarios, even if it wasn't something she did before me. i guess i just felt like being the dommy in this was where i thrived and it made us both feel alive and connected. but last week we had a rough scene that went way too far and she got hurt. physically nothing bad happened but emotionally, i could see the toll on her face and body language. after some time cooling off i apologized profusely and promised to take better care in our scenes going forward, to always make sure safety was priority number one. we're working through it, but now i have this lingering doubt about myself, wondering if maybe this whole thing is a facade or that deep down i’m not the person i pretend to be when we’re together.
