Is he being friendly, or is he hitting on me?

There’s this older guy I’m friends with who I was in a tafe course with and just got back in touch with. He wanted to talk yesterday on FaceTime and we did and now he wants to do that again tonight, for fun, when we’re catching up tomorrow. My goal was friendship. Is this guy hitting on me or being friendly? I have Asperger’s, so I can’t read social cues. Please help?

Is he being friendly, or is he hitting on me?
