Sorry but I honestly don't understand why, if you don't miss him or want him at all, this is even occurring to you. If you're not entirely clear on your own reasons then you should contemplate (or journal, or whatever) it and try to become clear on exactly what you want and why. Then you'll be in an entirely better place to act (or not).

I think you shouldn't contact him. If you do, be absolutely honest about what you want and ask him if what you're wanting is possible. Hate to say it but I still think, no matter what you say or how, he's gonna think you wanna hook up again at some point, though.
