I guess the short answer is it depends what YOU want.
It sound to me like you're not happy with the idea of "sticking it out and seeing what happens", but you're willing to do it in the hope that things might become more serious.
Whilst patience can be important in a relationship - I believe that if a connection is going to last the test of time, it needs to have plenty of energy and passion from the get-go.
Trying to convince yourself that he'll want you more later on, and want to settle down and commit to a relationship sounds like you're avoiding the painful fact that it just might not be what he wants.
What's going to change in the next week/month/year that's going to make him want to be in a relationship with you more than he does now?
On the other hand, if you're not that emotionally involved but feel like being in a relationship beats being single, maybe this is a "small connecting flight" that's going to see you through to the main international airport where you'll be swept off your feet by an Airbus A380.
