Search Results: testing a friendship

A friend of mine from college, at random, mentioned that his friends had been trying to set him up with a certain girl. We had never discussed anything of that nature before, as our friendship is very casual; we talk about assignments, shared interests, etc. He didn't say whether or not he was interested in this person... he just introduced the subject. And I didn't know how to respond to much of it, so it died out quickly.

My question is: Why would a guy mention this so directly to another girl? He seems pretty open with things, so I considered that it doesn't have any hidden meanings... but I wanted to ask other men.

We see each other fairly frequently, but we've never hung out outside of the campus. And although we have eachother's phone numbers, we've never texted. (I admit to feeling a little awkward, and that is why I haven't.) Was he testing my reaction? Am I overthinking?

Thanks.
