How should I talk to him without freakng him out?

Just talk to him about what he is doing this weekend and say what you are going to do and see if he wants to go with and if he likes doing what ever you're doing and see what he says back just flirt but not to much and if you get together with him dont tell your friends what happens between each other because something might get out and ruin everything unless you can totally trust them. Have fun and go get them.
