I recently met this really sweet guy. We met in an online forum. He goes to the same university, so we met up for a walk in the park to get to know each other. We both had a great time. He texted me three days later to talk. When he texts though, he doesn't respond for hours and leaves very little to continue the conversation. I think he wants to talk since he initiated the conversation, but I'm not getting much out of him. Could I make him text more or open up more? Or do you think he is not interested?
