Should I explain to him?
Okay so during lunch one time I was hanging with my friends, and my guy friend comes and sits next to me and we talked for a few minutes. Now I don't like him, but I guess someone thought I must've because I saw this guy that I was in a couple of classes before (who I used to fancy...) was literally staring at us. Now I was kind of confused, because we never really talked to each other. I used to think he liked me back but then he got a girlfriend and so I gave that thought up quickly.
Now I guess he thinks me and my guy friend are in some sort of relationship, but I don't want any rumors and stuff going around, so how should I explain to the guy that I'm not really in a relationship with someone? I feel kind of shy around him since I used to like him, but I don't know how I should let him know. I don't think I can walk up and tell him this.
Gah, I feel like a fifth grader asking questions like this.
