I am 37 yrs old and i have been diagnosed with adult autism. My older brother is 40 with a 3 yr old and a newborn. I think the 3yr old is kn tbe spectrum but its just a thought and i have never mentioned it. We had a falling out so i had to block him on fb i dont like confrontation. He in turn texts me dropping many f bombs and threats to kick my ass after a long pissing contest where every message he replies starts with f'ing retard. I had it i said i am retarded and lets hope your kid isnt im retarded i can tell.    He didnt it take it well but it worked to make him stop. Did i go to low?
