Am I a bad person for worrying someone will take my friend away
So I am solidly Aro/Ace, have known for my whole life. Most of the time I've been happy enough with my groups of friends, but they always seemed way closer to eachother than the were to me, until a year ago when I met my best friend in the whole universe. I love her to death, I would go to hell and back for her. we constantly spend so much time together, we agree on pretty much everything, and I have never been more at ease than when I'm around her. Its to the point where I've started thinking about the future, how nice it would be for us to move in together, to stay best friends forever. but she's not aromantic at all, and I know she will most likely want to a persue a romantic relationship. and that terrifies me because I feel like this person might take her away from me, that she won't need or want me as much anymore nearly to the degree that I need her. but I feel so guilty about this, I don't want to keep her from fulfilling that part of herself that I am unable to provide for her, but at the same time she is the most important thing in the world to me and I want us to stay that way. Am I a terrible person or being selfish for wanting her to stay with me? I know this is all theoretical because as of now she is solidly single, but what do I do if she does find someone she wants to persue romantically?
