How to attract him? help with confident guy!?

so this guy i like is really nice to me and sweet. he's very polite and he is the most respectful with me ever. we sometimes talk and he has become more easygoing cause he used to be super shy and could barely say two words to me. i think he might like me but i don't know how to act with him. actually he's a playboy and is very confident so i desperately need a good plan to get him!
