I have a cousin on the spectrum (not sure about specifics). I have never really been able to understand him, but this does not really bother me and I still talk to him. However, he is now in his teens and his behaviour towards me lately makes me a bit uncomfortable. He seems to forget that I am his cousin and is expressing behaviours which one would normally do towards their significant other. I cannot tell if he knows what he is doing, but it is making me very uncomfortable which feels really rude and wrong. At the same time, however, I cannot pretend that I am ok with it because it really makes me uncomfortable and I feel awful about it.
