<human>: I developed strong feelings for my best friend of 6 years sometime back. Only recently did I let it be known to her that I liked her before, key word being before. The feelings are (mostly) in the past. (I didn't want to tell her while I had them - feared losing her as a friend). Still unsure what actually made me want to tell her once I'd (mostly) moved on, but I did. Had no idea what to expect, how things might change between us. 

For a few months it actually seemed as if we'd grown closer. We were talking more regularly, she would call me more often, we would see each other a lot more and spend more quality time together. Everything was brilliant. I didn't quite know what to make of it all, was she trying extra hard to let me know that she'll always be my friend despite of how I'd felt about her in the past, and that those feelings wouldn't affect our friendship - or did she actually have some sort of feelings for me? 

Well, before I could ponder on that for too long, she suddenly became cold and distant. There was nothing I had said or done to cause this sudden change, I was being as I'd always been with her. And it's not as if she totally cut me out of her life, she still did get in touch with me but nowhere near as much as before. Our conversations were just not the same anymore too, felt as if she was reluctant to get too close. There was the odd occasion where we'd be having a wonderful time and I'd think that things were back to normal. And then bam, back to being distant and cold. It's as if she was really confused.

Why was she acting this way? Would really like some help.
