He doesn't sound very consistent, as evidenced by the way you describe him in the different threads.

Another issue: although some relationships work out great when both people have different interests and mutual respect for each other, it doesn't sound like you are content with the fact that you two do not have much in common. Once again, you cannot force him to be someone he is not.

Remember that he is not the only guy in the world. If you want to date someone you have more in common with and who will spend more time talking to you, then he does not sound like the guy for you (regardless of how much he likes you). Sounds like it's time to move on.
