Too Much or Too Little?

I recently told a close friend that I had been harboring romantic feelings for her, and wished that we had gotten closer. We had known each other for years, although we had never done anything social with just the two of us. For a while we were each in relationships with other people, and occasionally the four of us would do stuff. After that, I put out feelers, but they were never enacted on. This went on for years, warm and friendly but no closer than before.

I recently moved, and took the opportunity to let her know what had been going through my head: regret that we hadn't been closer.

I never heard back from her.

Admittedly, email probably wasn't the best medium for such a confession. Unfortunately, that was how we were communicating, and it naturally flowed in the conversation. I know, I know: I should have called her. Next time.

Without a response, I'm left wondering at how it was taken. Was she offended? Disgusted? Amused that I thought I might have had a chance? Angry that I hadn't said anything years ago?

Maybe she didn't even get the email. Or maybe she is having a medical emergency. Heck, she might even be dead.

Maybe she is just busy.

Either way, I'd like to know if it was too much, too late, or merely too optimistic. Even if it's painful, I'd like to know the truth.
