I have feelings for my professor
Do you think your professor shares those feelings?
I'm not sure, but I hope that she does.
It's pretty common to develop feelings for a professor. It would be a terrible idea to act on them though, and she would be acting unethically if she pursued a relationship with you.
It's all good, I'm going to tell her my feelings regardless.
I recommend you don't do that, as it could create a lot of awkwardness between both of you. You should just keep those feelings inside.
