>>I've thought of requesting that we take a break in a few months.

Always a good move when you're not sure if it's time to move on. It takes care of a lot of things at once, will reveal how clingy the guy is, gives you the space you need, and gives you time to think about whether or not he meant anything to you. The guy may also simply suggest a break-up, which is good for you as well, especially at this point when you aren't like to be very hurt by it.
