I think you should try to live more in the moment like he does. Take things one day at a time. I'm much like you in that I over-analyze, and the guy I'm seeing is much like him in that he lives in the moment. I think he really balances me out.

I wouldn't be so quick to dismiss him because he doesn't want to get married. There are plenty of people out there who have wonderful, fulfilling relationships and they never get married. Also, marriage is no guarantee of anything.

As for the age thing, try and not worry about what your parents might think. I know this can be hard, but you are an adult and you need to live for you, and not for anyone else.
