It usually means one of two things: 1-He's found someone else that has his interest enough to give him pause about you two, or 2- He's determined that you aren't the 'one' for him and he's going to gradually let this go. If this is the case, he should've just 'manned up' and been straight with you but thats hard for some people.
I wouldn't call him as thats not giving him his space, but its up to you to determine how long you'll give him to work this out. He is probably hoping you will just end it (which you should and if he comes back around, fine, but don't let this stay in limbo as it'll keep your feelings hurt and from healing).
If he comes back around within a week or so, great. His confusion will have cleared up and he'll be back solid. (Some men back off a little to decipher what they feel for you, right before they commit seriously or walk away for good). It wouldn't take long for this to happen so you don't have long to wait. Anything more than 2 weeks or so and he's waiting for you to walk away so he can be absolved of some of the guilt.
