I just told a good friend that I could not be there for her as often when she was in a relationship 2 years ago because....

I was a little in love with her. And, seeing her happy with someone else back then makes me a bit hurt. So I quietly walked away to eat my heart out for awhile. But I did keep in touch with her throughout those years, just not as frequent as before. Now that she's single, she asked why I did that. I cut to the chase and told her the truth. She's so cross at me now. I really don't know what to do. I might have to give up on this friendship.
