AITA for treating my coworker differently after she accused me of SA when i saved her live.

I'm a quiet guy and genuinely friendly. I treats all my coworkers as friends. About, 2 months ago, during a work lunch, one of my coworker started choking so i did the Heimlich thing to help her, after she's in the clear the others cheered i asked if she alright, she just nodded and head to the bathroom without a word so i didn't think much about that.

Until, two days later i got called in to HR for my "inappropriate" behavior, i was confused and ask for more details. That's when they told me that my coworker had filed a complaint stating that she felt my touchs when i was helping her was inappropriate, my body was too close and she "felt" my "private" touching her. I gave my statement and they put me on ice (i was still working with potential to be removed) while they investigate further. After a week i was in the clear. I return to working normally without fear, but i started distancing myself from the coworker, she tried to apologize which i accepted and tried to explained that she has to tell me that she has trauma but i still take precautions and only treat her as just colleague. I'm no longer talk to her unless needed to, always keeping distance, no longer inviting her out unless there're others. She could feel my hesitant toward her and how nolonger treat her the same as others, she tried to say that i'm being ridiculous and petty but i told her that i'm just looking after myself.

So am i the ah?
