So, I've known this girl for about half a year. When we first met we clicked like soul mates and even said it to each other multiple times, leading up to us going out. She told me beforehand she's apathetic and maybe aromantic, and asexual. I drove over 300 miles each direction to see her in person, we cuddled the first day for 8 hours watching youtube, she never deflected any advances. We realized later it was out of excitement, which caused her to break up with me.

Some of the particular things that stood out were that she said she did it to "Not feel broken". "Things felt off" and it's because she's aromantic. While everyone tells me she was just using me for her own purposes, I kept just trying to look past that, and her being aro didn't bother me. The break up hurt me and I just went on a downward spiral of mental health, and kept bothering her about how we could fix things. Which is my wrong, when she just wanted to be friends. Gradually it got her to be distant from me even as a friend and I got scared. I wrote her a letter explaining that I've finally let go not even a week ago, I guess I wrote it wrong because she stated that "I liked it at first but it turned into a love letter, it's obsessive and creepy" I only intended it to say "I still have feelings for you, but I'm fine being friends."

I sent her the letter, and it all just blew up, I freaked out, we argued, and now she's done, and won't give me the time of day to explain. Nothing works. She's gone. It hurts and is hard to let go. I want her back in my life, I don't care if it's as friends. What should I do?
