Is it normal that i still like him after all these years?

I guess from an early age, I discovered that I didn't "crush" as much as my peers did. I could name all the people I have had feelings for on one hand. Then, there's one that has persistently stood out. 

So I've known this person since elementary school, where I had an innocent crush that involved me being mean in order to conceal (and in a crude way, express) my affection. It was like Helga and Arnold for anyone who has seen the cartoon "Hey, Arnold!" 

Then, we parted ways when we attended separate middle schools. I thought I would never see him again...until I saw him in high school. 

From then on, our relationship evolved into this strange and unusual courtship where we weren't dating but referred to each other as husband and wife publicly. He initiated by literally proposing, getting down on one knee. Though I never confessed to him that I had a crush on him during this time, still we were together. We never went further than just lacing hands, walking/skipping to our classes, and mild cuddling when one of us needed comfort. Very respectful, very innocent. 

We received some flack, mainly because I'm black and he's white, but I grew up with both races (black family, all white classes and neighbors) so I knew I would be attracted to white guys as well as black. And it was nothing that I could do to help it. 

I always wanted to tell him, but chickened out multiple times. Then, another guy started expressing interest in me, and the "husband" was a little perturbed. Nonetheless, nothing manifested from this other guy.

Now, I'm in the midst of college, where there are hundreds of guys to choose from that I at least wouldn't mind hanging out with. But in the back of my mind is still my "husband." Recently we hung out, alone, joked about being a couple, especially interracially, and how cute we were. We share our dreams and aspirations with each other, even our religious and spiritual journeys. We share our intellect and subtly flirt publicly online. We sing duets and dance and laugh...and just have a good time. Everything is so natural with him...a little too natural. 

It's been almost 10 years since these feelings surfaced...and I don't want to just play as his "wife" any more. I want to know if we could ever be something more than just play dates. I don't want to come back from college and find that he's dating someone seriously while I'm still processing these feelings. And he's always quick to ask me about the guys in my life (which are never on his level). 

Is it normal to develop and harbor strong feelings for someone this long at such a young age? Am I just wasting my time? Should I just go for it? Or Am I just being delusional?
