I can relate. My stepdad repressed some things that happened to me and he was physically present at the time. Two examples come to mind. One, when I was 14, I tried to commit suicide and he and my mom shuffled me off to middle school that day - although I had taken a bottle of prescription sleeping pills and at least 50 Tylenol the night before. Two, when I was a junior in college, my mom held a knife to my throat and my stepdad was on the couch adjacent to me. Go with your intuition. Talk to a therapist about it, if you can? My stepdad in fact did later end up recalling these events...and was shocked that he could have repressed them like he did. Good luck.
