Profiles that you like will disappear from your search results, but no worries they do not go into thin air. If you had liked someone's profile , that user will receive a notification that you had done so. That user will have a chance to review your profile and if he also likes you, then you will receive a match notification and now be able to start a conversation. If you haven't received a match, unfortunately the other user didn't find you as the next amazing roommate. Don't give up, keep on liking!
