Is it normal for a guy to follow me all over campus? idk

I think the guy that asked you out might have had inadequate social skills and thought you were cute so he thought he would be brave and ask you out. Go the direct approach method rather than the normal "Hey, you're cute, here's my number, text me, let's hang out sometime, what classes do you take" small talk approach.

I'm assuming that your answer made him think that you would eventually talk to him because, to be fair, your answer was indirect and he was probably hoping that you would talk to him.

I know that you were probably trying to let him down nicely, but some guys don't have enough experience with women to know that so I would suggest that the next time you encounter someone who is interested in you that you do not have interest in, just tell them straight up that you are not interested. It's a lot less awkward than being followed for a week by some poor soul that thought you literally meant that you would keep him in mind. After all, how else would you have contacted him if you two didn't know each other?

He could be an aspie.

It just sounds like he's persuing you. If he was the right guy it would be cute. If you don't like it and you tell him straight up no and he keeps following you, then it's a problem. You really don't know if he's a creep at this point.

Asking you out is one thing; but following you around is creepy.

The fault is entirely yours. He had the courage to ask you out. You should have given him a definitive answer (yes or no). Now you have a stalker. You will need to confront him (in a public place with lots of people around), and tell him that you are not interested in him.
Be observant and careful in the near future. Do not go anywhere in public without someone with you. If he continues to follow you, then is the time to contact authorities.

I had this once. Just watch yourself just in case, make sure you're not alone all the time. At least do that for a while.

I had a friend from my last class offer to drive me to my car if it was parked on the other side of the parking lot. Walking is scary. Especially if its dark, you have to watch out.

But he's probably just a harmless guy that thinks your hot. If he ends up asking you again, and you really don't feel comfortable, just say that you're sorry, but you're with someone already. Or say the truth. That you're sorry but you really have no idea who he is, and you're really not interested. If he begins stalking(like real stalking), you need to tell someone.

I agree with Suck, you should've given him a clearer answer.
This man is stalking you... and his actions aren't normal at all. You need to contact the authorities and never go out on or off campus alone. You could confront him on this, but I don't think it's a good idea as he could be mentally unstable and try to harm you.

That's just weird. It happened to me once, this really tall dude just started following me everywhere and asking me to meet him places. Finally, he eventually left me alone. But your stalker may not do that. No, It is NOT normal.

Creepy, you should have campus security on speed dial.
