<human>: I've known my best friend online only for 3 months, but I love her more than anyone else I've ever known, at first just as a friend I thought. A couple months ago I started to have feelings for her, and I told her, and she freaked out a little bit, so I just threw those feelings aside to preserve our friendship. I've confided a lot of my emotional and mental health issues in her, and she knows I'm unstable, couple that with the fact that she has a boyfriend in the airforce (She likes the strong manly type, and I'm well... not either of those...), plus some other stuff I'd rather not get into on this subreddit, and means she'll never think of me in that way; more like a needy, broken little brother. 

She's going through a lot right now in her personal life, but all of the sudden these feelings are coming back, way stronger than before. She means the world to me, and I don't want to ruin what we have, but I know, against all fathomable reason, I want more. I'm worried that if I tell her i have feelings for her, even with the subtext of knowing that nothing will ever come of it, she'll freak out more, because she's already under a lot of stress, and push me away, which I can't take right now. Do I try to bury these feelings, do I just live with them and hope they go away on their own, or do I tell her, and just hope she understands?

<bot>: I'm in love with my best friend who will never love me romantically, and I'm worried about piling on her current stress load, but I still feel like I should be honest with her.
