Dating gives us a chance to experience some new people and new feelings. I don't think it's a waste of time. We learn from what we do, or so we've been supposed to learn all along
I don't. He isn't trying to waste your time (the fact that he's honest about his feelings proves that. Do you know how hard it is to find a dude that'll flat out say something so simple and yet telling?) and he isn't necessarily afraid of commitment; he may be open to something serious but it isn't all he's after. He understands that it's okay not to see a future spouse in every person you give your time and affections. He's probably taking life at his own pace and isn't in a rush to settle down - and nothing is wrong with this mindset in your teens and twenties, as you should be your own biggest priority in these years (some people in their thirties and forties still feel this way, too - after all, it is not a life goal of everyone to end up married). Sometimes we get so caught up on one specific end result that we avoid something we aren't certain will give it to us, and in limiting yourself like this you could miss out on great happiness.
