<human>: Ok so this might be a little confusing but I would very much appreciate some opinions. For clarity's sake I will use female pronouns for my friend. I am bisexual, and have been in relationships with both genders. I have a close friend who was born biologically male. I met said friend before they transitioned and was very much attracted to "him" through looks and personality. Both of us were in relationships while the other was single so there wasn't really a chance for me to pursue my friend and I'm sure that friend didn't realize I had any kind of feelings towards her. My feelings weren't very serious at all but if she had asked me out I would have said yes. 

After a few years of us knowing each other she came to me one day and confessed that she was actually female and wanted to transition. I was glad that she felt comfortable enough to confide in me and supported her as much as I could through the entire process. Now she feels like how she should have been feeling her entire life, she is much happier, and much more confident and I am extremely happy for her. We're both single now and recently she confessed to having feelings for me, apparently she has had these feelings for a while but didn't feel right asking me before she was fully herself. I told her that I cared about her very much and would have to think about it. So the problem is that I'm just really confused. She is a very pretty woman, but I was much more attracted to her before she transitioned. But I feel like if I hadn't known her before I would have returned her feelings now. Is it super messed up of me to turn her down because I was more attracted to her as a man? Also I don't want to lose her as a friend so if I were to turn her down how I would do it gently?

Can you provide a brief overview of the text?
<bot>: Friend transitioned from male to female and confessed that had feelings for me. I had feelings for her when she was male but now not so much. I am unsure of how to proceed.
