In order to handle a Hot-and-Cold Guy, you will need to create an amazing experience. Then, you will need to draw back. You should, then, repeat this pattern over and over again. This should make him want to be with you more. You will need to make him crave you. If he isn't craving you by then, then you need to have a talk with him. Be straightforward, in your conversation. Let him know that you need him to really be with you or you will leave. Let him know that you want a guy that wants to be with you. If it isn't him, then you will find someone else.
