If the guy seems only interested in friendship, set limits when it comes to time, frequency of hanging out, clingy-ness. For instance, you should not let him touch you in certain ways, at the same time, let him know if you are only refusing to be touched because you are not dating. If he invites you to his place, you should remain at the door or just get in for a short period. This will make the guy realize that if he asks you out on a date and you become closer he would be enjoying some things that he is not enjoying now that you are not in a relationship.
