Is AUTHOR wrong in the post ? POST : I have been friends with a girl with autism (I'm not sure whenever it is severe or not, but I'm pretty sure she is high-functioning autistic).
I have been friends with this girl for around 1 and a half years, but in the recent months she started to make my friends and I really uncomfortable.

We are in secondary school (Year 10), not sure where in American school system. 
I have C-PTSD, and I am sensitive to touch. I have explained this to her many times but she continued to try and touch me and push her limits. She also did this to my friends who also don't really like it. This included getting her face extremely close to us, jumping behind us to scare us, and asking us gross things. 
This went as far as her asking "Can I puke in your mouth?" and other gross questions. 

Also, she kept complaining how we are never there for her and she doesn't like it that she always has to initiate a conversation first, but in the past, when we shared our issues, she never comforted us in any way, and didn't provide much support. Whenever my friends or I started a conversation in a groupchat (which was often), she never replied properly, but only ever said "lol", or sent us the okay thumbs up emoji or the rainbow emoji (it was always the messenger emoji you had on the right of your screen).

My friends and I have recently made a "cult" as a joke and we made a little support system with our own inside jokes and such. We sometimes go out together, and do random stuff. She called this stupid and basically insulted all of my friends. 
She also lied about my boyfriend (back when we were not together), and said that he said I should kill myself, of course this wasn't true and I hope it is justifible that I got a bit angry. 


I know this does sound mean but she has a really not nice odour, she smells like musty rotting wood which is not pleasant to be around, and I know this might be because of her situation, but I think she rarely washes her hair. Which normally I wouldn't have an issue with, but due to her always getting close, sometimes was too much. 

We have explained this to her many times and most of the time she used her autism as an explanation, but refused to attempt to change. Although she had started to ask for permission to touch us (which still comes off as creepy). 
I think I should be allowed to choose who I am friends with and who I am not, and shouldn't just accept what is going on simply because of someone's autism, especially when it just makes all of my friends uncomfortable. 

I only really talk to her sometimes because of a mutual friend who doesn't want us to argue. 
I hope I am not too much of an asshole, I just want to hang around people who get my sense of humour and I feel comfortable around. I'm not doing this simply because she's autistic. 

Tl;dr : She makes us extremely uncomfortable, insulted us, and has double standards. : /
