He needs to put in as much effort as you in order to make the relationship work. Since he is in the process of figuring out personal issues like sexual orientation at the moment, it seems like he needs time before deciding whether he can committ to you for real or not. But don't sell yourself short. Think critically if this guy is worth the hurt he's putting you through. If not, take steps to move on. You don't want to continue with an on again / off again relationship as you will only feel increasingly hurt.
