Wow! Confront him immediately. Then invite to go home and cut him out of your life. No one needs that kind of toxic BS.

I know I'm chiming in late on this but I have to lol!

Your son is a child and your brother (also a child! but..) logistically is supposed to be an adult. That home is your child's safe haven and I'll be damned if I'd ever let him walk through the door again!

Just because they are family doesn't mean you have to deal with their BS and as a parent of a special needs "amazing" child, we are their advocate and it is our job to be on their side!

End of rant...my apologies if I offended anyone but these type of adults really yank my chain!

You aren’t alone!!
I have found that my real “family” is with other parents of kids with Autism!!
It you just remember it’s Their problem of being cold hearted
And ignorant not your loving and kind self and son’s fault!

I had a so-called friend staying at my apartment a few months ago, he was supposed to come for a week and lasted a day and a half and in that time went off for a walk for the best part of two hours. He then said being around my son was like torture and was unbearable and that he couldn’t stand it. I told him to leave and that he wasn’t welcome and I was quite disgusted really, that a grown man could behave in that way. That’s how I deal with people I just tell them to get out of my life because so many are out for themselves and they’re not there to support others. It’s makes the bond with me and my son so much closer, as I totally understand him, even if others don’t . They all have their opinions and their strategies but to be honest they don’t have a clue. Have no qualms now in cutting people out because my life is difficult enough in order to give my son the best attention possible. I do not need negative people are negative energy around .

I am a bit militant I guess, but I’d not so politely tell him to go somewhere extremely hot run by a guy with horns and a pitchfork. Mess with my kid or interfere in my family and whatever relationship existed is over.
