I'm going to talk to a guy that my friend was supposedly also talking to
Why do you want to talk to the guy?
I wanted to meet him to see what kind of a person he is.
It is okay to be curious about people your friends are dating but you should be careful not to be too involved. Your friend will not appreciate you interfering and ruining things.
I just want what is best for my friend.
But, the point is not to get involved with your friend's romances. You should find your own love interests.
