Yeah, we'd been "friends" for years too. I kept going out of my way to get her to talk to me but she literally refused to comment even acknowledge I existed. Then the fake bitch had the gall to act like she did this because she ACTUALLY thought it was the most mature way to handle at the time. It hurt. A lot. It was fairly recent too, and even writing this I can tell there's still anger in me.
I think you can try to get in touch with her, which you already have. I'd even say give the friend the benefit of the doubt if it's been only a few hours, or even just a day. Sometimes stuff happens or people miss a text, it might be worth sending
one more text (assuming you only sent one) just in case. But if it's been days, or you've sent a few texts and been ignored? It's not your fault and it's not responsibility. The other person is the one who is in the wrong, and who is being immature. Even if they don't want to be friends, you at least owe the person an explanation rather than a cold shoulder. And, ultimately, if a "friend" treats you like that, I won't say they weren't your friend, but the person is a very bad friend, a very self-centered friend, and a very insensitive friend. And I'd say when they've truly been blowing you off, at some point you need to start distancing yourself from the friend and just accost it's over and, in a sense, just call it off to yourself so you can stop stressing over it. It'll hurt, and it'll be sad, but that's okay because the person was your friend (even if said person was a poor one) It's the best way of healing if the person is unwilling to talk or work things out. And again, a friend giving you the cold shoulder is a reflection of
that person, not you. No one deserves to be treated like that by someone who is, at that moment, a friend. You are not to blame for how poorly this friend is treating you.
That said, I do think it's important to look over your behavior as objectively as you can to try and see if you did something wrong. If you really can't come up with anything, all the more reason to drop the friend. Chances are there was some kind of mistake being made throughout the relationship. If that's the case, work on improving or fixing it as you move forward to avoid this in future friendships. This one is too late to salvage if the friend won't even talk to you, and it's probably not one worth salvaging either, but you can learn valuable lessons from it for future relationships.
I hope this helps some, and I'm sorry it's happening to you
