A friend of mine claims that a guy in my PE class has a crush on me. I noticed that the guy follows me around sometimes and does the exact same thing as me occasionally (he also take quick glances at me a lot!). I told my friend that it's only about 2 months since school started and this might not mean that he actually likes me. What do you think?
From what you said I'd say there's a good chance he has a crush on you.
Maybe. Talk to him.
Either likes you and is shy or he's practicing to be a future stalker.
Fear of rejection may be stopping him from expressing that he likes you.
