real event - I think I actually did it

i’m worried i had a racist reaction to my bf bc we were walking to a train platform i turned around and couldnt find him but he was tgere amongst a group of men and i instinctively put my phone away and felt a panic like oh no they mught try to steal your phone and idk if that was bc i noticed my bf (who is brown) and he was the person I reacted to out of racism (I know I do have implicit bias and I am trying to work on it every day) or if it was general bc i must have registered him being there without looking at his face properly and there was a bunch of peple walking towards me and when i put my phone away i think i was looking at them but i think maybe seeing my bf standing there without realising it was him was what prompted my initial thought and reaction? I can’t remember if there was an initial racist thought but straight after it happened I thought there had been so maybe I’m just avoiding accountability but idk. I feel like I should be honest with my bf about this?
