Any ideas on how I can fix this?

So yesterday night while I was at a party hosted for me which was celebrating my going away to South America for the next few months for volunteer work I was backing up my old contacts list from my old phone. When it finally finished I checked through all my contacts just to make sure that none were missing. Fortunately, none were but I had a few extra add on. One of them was a girl who I was friends with for a while but after an issue occurred we stopped talking and agreed to delete each other's numbers.

Now, I felt kind of nostalgic in that moment and I decided to write her this message:

"Hey, (name) I found your number in my phone and decided I'd send you a text before I leave for South America in the morning. I just wanted to say that I'm sorry for whatever I did to make us stop talking and I hope you have a great summer. This is (name) by the way."

Her reply back?:

"Delete my number and never talk to me again. Bye."

Harsh much? And it stung all the worse considering for a long time I had some pretty strong feelings for her. I was pretty distraught in that moment and I replied back with.

"Alright, I guess. Like I said I'm sorry for whatever I did. Best of luck."

I don't know why but I want to try and reclaim my friendship with her despite those sharp words. How on Earth do I achieve that considering the current circumstances? If it's impossible please just be up front and tell me that but I was wondering if anyone had some creative ideas.

Well, do you know what went wrong between you? Once you find out why she's being so icy with you then it should be easier to sort it out. I say just send her a text/letter saying something like "I don't know what went wrong but I'd like to rebuild our friendship, I'm sorry about everything that happened to make us stop talking but could that not stay in the past?" you get the picture. Maybe if you send that soon she'll have time to think about it before you get back.

Can I ask, if she's treating you like this seemingly with no reason at all then do you really want her friendship? You don't know, she could turn on you in the future as well. Just think about what you'd really be gaining from starting it up again.
