What does it mean when a guy tiring you?

I was standing waiting for the bus and there was a guy who noticed me and looked at me and after a while he was walking and talking on the phone and looking at my body, he was walking in front of me and when I got on the bus he was looking at me too (he was tiring me) and I tested it and I was going to get off another station ( Not what I want) After that, I saw him, he was going to get off at the same station, and when I didn't go away, he didn't go and he was still on the bus, but then I could escape from him
