Weird behavior from a gym member

Update: the gym BANNED ME after posting a google review on their lack of action.

I’ve been going to my gym for over 2 years, but lately, an older man there has been making me uncomfortable. He asked me out once, and I politely declined. Then, one day after the gym, he followed me as I walked home (I live really close) and insisted on offering me a ride, which felt odd.

The next day, I happened to drive my boyfriend’s car, and he asked me what new car I was driving because he didn’t see my usual one. That creeped me out, so I stopped going to that gym for three weeks.

I reported his harassment and stalking when it first happened to the gym management, they told me there is nothing they can do as it happened outside of the gym. They told me they are monitoring the situation. It didn’t seem like the management wanted to help at all when I first spoke to them.

When I finally returned, I adjusted my schedule to avoid him, but I still ran into him as I was leaving yesterday. A few hours later, as I stepped out of my house, he drove by, rolled down his window, and asked if “we were okay” and said he didn’t want any bad feelings between us. It felt really strange that he happened to see me at my house.

He lives near the gym, so I guess it’s possible, but it all feels like too much of a coincidence.

What should I do? is this something to be concerned? I’m also really applauded that the gym hasn’t even spoken to him or giving a warning.

Update again: WOW thank you for the great advice and support everyone!! I posted on social media to bring awareness as this was not the first time harassment at this gym has gone unresolved and female members were forced to leave due to feeling unsafe.
