Pardon my French, but who the fuck told you that you seemed too soft or that it wasn’t a huge deal? That incident was horrible, and you could have ended up as a statistic. I suggest writing the owner of that gym and telling them about the incident! Threaten to go public on all the local pages if they don’t take action and make a public comment about this - we have to work together and do what we can to report things, if only to spread some basic info to other women.
I’m so sorry this happened to you and I hope you’re okay now, and I urge you to seek out empathetic and loving friends to speak with about this :(
