Uncertainty

These last days I’ve been having some sort of “issue” with my best friend (well, now I’m not sure if I should keep calling her that). The thing is, I need the opinion from people who don’t know her so I can have the most objective points of view. Maybe the problem doesn’t exist and I’m just having my usual insecurity issues, but somehow this time I don’t think that’s the case. Anyways.

I could say the problem started around 6 months ago when she started having some sort of romantic feelings to a certain guy. This ultimately caused us to become more separated from one another. The problem here is that she thinks that all the fault from that is mine. Nevertheless, I tried to ignore those feelings and tried to be as friendly as always, like if nothing had ever happened.
It didn’t work.

Sooner or later I would find out how easily I could be replaced by someone else. I’m 99% sure that she now has a new best friend, and hasn’t had the nerve to tell me that I’m no longer her best friend. But honestly I don’t understand her anymore.

One week she is really kind like if nothing has ever changed between us, and the next one she doesn’t even say hi to me or even look at me, like if I didn’t exist. And right now I’m feeling really sick of having her as a priority while I’m just an option for here, and not even a second or third option.

But on the other side, I don’t want to believe that this friendship has ended just like that. It’s been a long time since someone called me their best friend, and if I don’t have her, I won’t have anyone else who will call me that.

What should I do? Should I try to still be her friend? Should I give up already? I’m so confused…
