For the past year my nephew has been very distant to me. He is 15 and autistic. We never used to have an issue but now whenever I see him he runs away or puts his hood up and refuses to look at me. He has even refused to be in the same room as me and I have had to leave the room as he wouldnt even walk past me. Initially when his parents asked why he said I asked too many questions so I stopped asking questions to try and make him more comfortable but instead of getting better it has gotten worse. Today he told them I make him feel anxious and he doesnt know why. Is there anything that I can do to make it better? I dont want to force him to talk to me, in fact I know I wouldnt be able to as he would just run away and put his hands over his ears. So how can I make the situation better if I cant talk to him? I was waiting it out just hoping it would get better but it's a year now and it's getting worse. Any advice would be greatly appreciated.
