Ending a friendship?

I think I might have just lost a friendship. There is this girl I have been friends with for several years. The relationship has always been just platonic. Overall, I consider us pretty good friends.

Over the years I've developed feelings for her and I told her how I felt. To make a long story short, she didn't feel the same way about me. So, I told her I respect her decision but I still wanted to be friends, just like we always had.

The problem is from time to time, she will ignore my emails and not answer some of them. This is how she is from day one. But this problem has gotten worst in the past few months, I don't know maybe it has something to do with my feelings for her or not. But I have made is clear to her that I'm okay for us to be just friends, and I sincerely mean that.

So I sent her this email after I haven't heard from her and told her that it bothers me that she doesn't reply. I said it in a really nice manner, not rude or anything like that at all. Still, I haven't heard from her. I know she is reading her email.

My question is should I try to just forget about her? Or should I at least try to find out why she is not writing me back? Maybe calling her? I do feel sad that I might loose this friendship and because it might have something to do with my feelings for her.

Did I do the right thing by telling her how I feel? What about the way she has always been by not writing me back from time to time? I feel like I'm the bad guy here, what should I do?
