How do I bury my romantic feelings for my best friend, knowing they are not shared?

Anonymous
My best friend is a girl. I am a male, early twenties. We have been friends for 4-5 years now. We speak on a daily basis and we are by each other's side.

At first I didn't see her as more than a friend. I want to mention that. However the past 1 year or so, I have started developing romantic feelings for her. Not to the point where I can't date anyone else, because I have, but to the point where I get very jealous when she talks to a guy, when she sees someone, when she tells me this guy is so nice and that she has a crush on him.

And I have realised that I don't treat her as my friend anymore. I don't show her this, but I see it in me. I think about her throughout the day, I get excited when she messages me etc. You know, all the stuff when you like someone.

I know for a fact feelings are not mutual however. And I am honestly tired of this. I just want her to tell me about others without me giving a flying fuck.

How do I go about this? Because I have a hard time.
