About me: **I have the syndrome of Asperger, so I might see things different compared to a 'normal' human.** Only my family knows about my syndrome and I'd like to keep it that way.

*Little backstory:* I met a girl a few months ago. We were friends quite fast, because we have a lot in common. We both talk to each other online, because we are both a little awkward IRL. We both go to the same school and stuff so that is not really a problem. 

The problem comes when it was around January. In Jan there was a party for people and she went there. She said something about it and I just wasn't paying attention. I wanted to be alone, so I didn't reply to her messages. She started to panick about it and I solved it. I read a book about relationship and it said that a man sometimes needs alone-time, but has to tell his counterpart about otherwise you'll end up hurting her. So, I told her I wanted to be alone, so she let me be. 

One week later she sent me a message just saying 'hello'. I still wanted to be alone and ended up saying nothing. After that I didn't receive anymore messages from her, nor did she talk to me IRL. I wanted to apologies again for being rude or antisocial, but a lot of stuff came up(exams, projects and stuff). It kinda slipped my mind.

It's now Feb and still nothing happened from either sides. Me being autistic has worried many times about how to apologize. I could write a long letter about being sorry or make something to make it up. Still I have the fear of being rejected you know. That's why I am asking reddit.  

So what should I do?
