Guys who have accidentally knocked out your girflriend/wife, what happened?

So this happened yesterday. My girlfriend has been doing MMA, kickboxing, and judo for the past 6 years. Her and I spar occasionally. She's fairly small at 5'4" and 125lbs whereas I'm 6' and 190lbs. She always tells me to not take it easy on her but I always make sure to pull my punches because even though she's trained and I'm not, I'm still much bigger than her and don't want to hurt her. Well yesterday, we were sparring like we do and we started goofing off a bit and I started spamming spinning backfists intentionally not getting anywhere close to her. Well either she was attempting to move in to strike or come in with a surprise takedown (she says she doesn't remember) and timed it wrong and I caught her flush on the jaw. Her legs immediately went limp and she flopped to the ground completely unconscious. I immediately knelt down next to her and started calling her name trying to wake her up. She finally came to after about a minute and was out of it. She knew her name and where she was but had no idea what happened so I took her straight to the ER and got her checked out. Doctor said she had a concussion but she'll be okay, just needs to rest and take it easy. I can't shake this guilty feeling though. I know it was a total accident and I'm not a bad person for what happened, but it still feels bad. She's been knocked out two other times during her combat sports career so it's not new to her and she's been totally cool about it joking around about it and all that. I try to joke about it too with her, but I still feel terrible about it. Has anyone else ever accidentally knock your girlfriend/wife out cold? If so, how did you get over the guilt even knowing it was completely accidental?
