Theory #8: Future Time Travel Paradoxes

Let me start by setting up the scenario. I'm going to call you reading this, A~You. Future you will be known as B~You. So let's assume that A~You could travel to the future. A~You see's B~You. Would B~You from the future be expecting A~You? Would B~You have known that A~You was traveling to the future to that exact day because B~You was once A~You? The only one flaw with this is that A~You would only run into B~You if A~You traveled back to the past after meeting B~You. If A~You never traveled back. B~You would never exist. I'm just unsure whether B~You would exist in the first place after A~You traveled to the future.
