How can I back off?

So I’ve been seeing this guy for almost 2 months, we’re exclusive but not official. Recently I’ve been a little worried that I like him waaaaay more than he likes me. I’m scared to death to get my heartbroken.

So my question is: *How do I back off?*

Specifically, how do I reign in my emotions and feelings for this guy so if he breaks my heart, it won’t hurt as badly? I am so done with the hurting. I know it’s what I need to do, but how can I pull back without him thinking I’m uninterested?

Is this one of those things where I just have to let it happen, and be hurt in the end?

EDIT

Thank you ladies. I really like all your advice! It’s just hard because I have been putting all my energy into him. This is my first somewhat relationship since a really bad breakup, and I think I’m just so afraid of getting hurt I’m putting too much into it without getting very much back.
