Give it time, go slow. Be a friend first. Friend=not threatening; Romantic partner=very threatening. It takes us a while to get used to a new person, new places, new activities. Most of us are uncomfortable being touched or hugged by strangers unless it's the briefest of hugs. Try to meet somewhere he feels comfortable. Suggestions - quiet place (restaurant, book store), not much activity, one-on-one is better, not having to follow multiple conversations or compete with noise. Movies may not be the best choice for a first meeting, not enough private interaction and too many people milling around, but you would have that as a "topic" afterwards. Even walking around the mall, seeing what he likes and what you like can break the ice (music, videos, books, magazines, computers, etc). Ask him questions, but don't push, and don't make it sound like he's being grilled. When he answers, find out more about what he said, later respond with your own "stuff". Or even, gee, I've never done that, do a lot of people do that, is it something you could teach me. Just non-threating conversation. Show an interest in what he says and does. (If you really aren't interested, perhaps this isn't the person for you. If he isn't interested in "your stuff", he may seem bored or rude and not know how to handle it.) Avoid personal topics in the beginning. What's your favorite thing to do, favorite author, favorite game, foods you don't like, etc. He may not know to ask you questions, so you may have to say things like "guess what I did for fun last week". Or make it fun, joke with him and tell him it's his turn to ask you a question. Be prepared for anything, he may not know what's appropriate
We're all different, but there are generally two extremes - Most of us rarely talk and don't know how to keep a conversation going. (Describes me - I married an extrovert, but I later learned how to "do" conversation.
). Some talk non stop and don't know how to let others participate in the conversation.
Hope your meeting goes well!
