Find a hobby the two of you can share like biking or dance, etc.
Think him as a friend too! Do things that you do with your friends. Start slowly and progress. You can play games together! Enjoy!..
Try out what he likes to do to know more about him.If you find some common hobby,yes way to go!Also what about let him take part in some of your activities? haha These are what I actually did...Lol When we started out relationship I didn't know him so much except I had a crush on him..
With my gf you want to make friendship, it fine just say her hello
