My best friend is in love with me and idk what to do?

Talk to her. Tell her that you think you may have feelings for her, but since you've never liked another girl, this is a strange situation for you. She'll understand, trust me. And you don't need to tell your parents about everything if you're overly worried about that. But talking to her will be the most important thing. You could even send an email r something if you're afraid you won't be Abe to say these thins directly to her.

And as far as you feeling unsure about your sexuality, many people are, at least to the smallest degree, slightly attracted to both sexes is a lot of cases. Have you ever heard of the Kinsey scale? It runs from zero to six, where zero is completely absolutely straight, and six is pretty much as gay as you can get. Three would be completely bisexual in this case. You could try labeling yourself as a Kinsey one if you think you need to, but really, you could just call yourself "straight but I may be attracted to this one really beautiful girl" kind of deal. But really, I'd recommend worrying more about how you and your best friend feel rather than about what you would instead need to label yourself.

 

Just to clarify, your profile says you are male, but from this post you are clearly female or female identified?
Just bringing this up in case you made a mistake editing your profile, you might want to change that it says male if thats inaccurate.

As for your friend, i think first is first you just need to talk to her. I know its confusing for your and very difficult and upsetting but it is for her too and if you are best friends then its not good at all to ignore her. Coming out to someone is a very difficult not to mention confessing her feelings for you must have taken a lot of courage and fear and trust.

Whether or not you have feelings for her, you're her best friend and you should do what you can to show her support and let her know that there is nothing wrong with her.
I guarantee you right now she probably feels a hundred times worse, she might feel that you are disgusted by her or you hate her or no longer want to be friends because of her sexuality.
Unless you feel those things then it is best to be a good friend and assure her that you're okay with her sexuality and are willing to talk to her about it and that you were just shocked or overwhelmed by her confession.

I know things like this can often make someone question their sexuality, but it isn't a rush or panic, its something that needs to be taken slow.
You two need to talk and reestablish your freindship and in the midst of this you need to do your own soul searching to determine how you feel about your sexuality and how you feel about her.

There's nothing wrong with not being gay or feeling the same way for her just because she feels it for you. Even if you aren't gay or you don't feel the same way for her, the important thing is just being a good friend. Be honest with her and let her know you support and care about her and your friendship with her and that this wont come between it whether you are gay or not.
She must be terrified at this point, not knowing what you are thinking or whether or not you despise her.

The first step was seeking out advice and establishing your confusion and thats very good, but strangers can't really tell you who or what you are, hopefully we can help guide you but no one but yourself can determine your sexuality. You need to sit down and talk to your friend. She came out to you and told you something that isn't easy at all, it was a very big and terrifying moment for her and right now she needs to know that her best friend is stil her best friend.
