Was my aloofness the source of the problem? (Aqua)

I belong on two different forums, this one is female dominated, while the other is male dominated (heavily, I might add. Popular site) and have learned a lot about the male mind and how they can easily be misunderstand by females. Anyway, I've realized that I can't put the entire blame on the Cap. Even though I don't have those romantic feelings anymore, I can't help but wonder if my aloofness played a huge part in our disconnection.

To be honest, he did most of the work, while I sat back and had him lead me. 9/10, he initiated contact/get togethers. It felt as if he was more invested and I just took it all in and didn't really recriprocate, as much as he did anyway.

I was interested, but I couldn't and wouldn't let it be known in the same intensity he was showing it (Telling him I liked him was one of the hardest things I've EVER had to do. First time I ever admitted to genuinely liking someone). How does that affect a Cap?

I'll accept any form of advice.

I was in denial but I was more aloof than he was and yet I was complaining about him keeping me at arms length. I regret it somewhat, but...too late now :/
