My TA asked me out for a coffee. Does he like me?

I used to have conversations with one of my TAs last semester from time to time. He emailed me the other day asking if I still have his notes and if I started reading the book he gave me. I mentioned in my reply I enjoyed conversation with his last semester and hope to continue at some point, and he said we could go for coffee sometime and continue our discussion on physics, and we emailed back and forth for a bit, and he asked me to go for a coffee this weekend. Do you think he likes me? or am I over analyzing because he really just like to talk about physics.
