<human>: We only dated for a two months last February (not a terrible break up; he broke up with me) and I recently started trying to talk to him again after we ran into each other at a local restaurant. I'm not specifically looking to date him, but I miss talking to him as a friend. 

We are two completely different majors at my university (I'm art and he's science), and since all of my friends are the artsy types, it's nice to be able to talk to someone out of that general area. We have a lot in common and we're both always geeking out about tech, videogames, or science in general. 

However, I'm not sure how to go about this. He says he wants to be friends, but I'm the one who usually initiates conversations and he seems to have little or no interest in talking to me on his own free will. He's a real genuine guy so I know he's not the douche type to lie about things like this. How do I know I'm not bothering him or intruding on a place where I'm not wanted?

Can you condense the text into a few key points?
<bot>: trying to be friends with my ex. He says he wants to be friends, but I'm not getting much effort from him.
