Questions: Guy's Behavior

I talked to a guy here before and he said he would do it out of the blue.. I think its kinda nasty. I wouldn't like that but I was wondering if its normal?

So there’s a guy at the gym that stares very intently at me. Like he holds a gaze for multiple seconds. He tries to make eye contact with me and holds it until I look away. He stares at me when I’m working out, he is intentional about being around me. Whenever I leave, he leaves right after me, and then walks to his car and stands next to it, and then just stares at me while I drive away. He did this twice. The next time he left after me, he waited by the door and watched me leave maybe because he realized it seemed creepy and he didn’t want it to be like that. A couple days ago he actually left before me and I thought that was so weird. I left and I looked over for his car and it wasn’t there so I assumed he left. But then, once I got to my car, he had actually pulled his car around to be right in front of mine, and he was standing outside of his car just staring at me. So then I thought maybe he’s a stalker. But the last two nights he hasn’t even been at the gym and he knows I’m there. Wouldn’t he go to the gym if he’s as interested as he seems? I’m so confused. Is he waiting for me to talk to him? Can someone please explain any ideas? He’s pretty good looking. Very strong Hispanic man probably in his 30s. ( he’s very good looking, so doesn’t seem like he needs to be a creep) I’m 42 and get a lot of looks at the gym. I’m in great shape, tall, long blonde hair (above average looking) also, I’m married and he’s probably seen my ring.
