First, knowing about your feelings to this level is a maturity. Second, we all know how our age is an affecting factor when it comes to considering relationships. The way I look at it is, if he was the one, you would've loved him dearly and wanted to have all the best memories in the world with him. But, now judging from what you described, I think you're just wanting to settle not in love with him. And all I wanna say to you is, you can always fall in love and experience all the amazing things as long as you let yourself.
