What does it mean when a guy says your asking too many questions?

Perhaps it is his way of telling you he is not interested. Normally if you have just met someone and you like this person, then you ask them a lot of questions because you want to get to know them. However, if he tells you he he does not want you to ask him that many questions, it is -sorry to say that- very plain that he is not interested in getting to know you.

he seems rude. find someone betetr. unless you were asking way to many and kinda scaared him. the question asking should be reciprocated on both ends.
