At this point in time, there is a chance that he really likes you and is intent on putting all of his attention on getting to know you.
If he were to continue maintaining an active online dating profile, he may get really distracted and he may not want that.
Hence, he may have cancelled his online dating profile in order to allow himself the opportunity to show you more of who he really is and also learn more about you.
