I'm not so sure he's manipulating the situation. It could well be that he thought that you were disinterested and is now watching your actions to see whether or not you are into him. In short, you probably have some making up to do.
If you really don't want to make up for your earlier display of disinterest, then have a conversation with him. Talk about how you messed up initially but would like the future to be a 50/50 split of showing of interest.
Nothing is ever solved with lack of communication.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
