I'm technically neurotypical but would say I have some signs of being on the spectrum. My partner was diagnosed as a child. He has a great job and a couple of close friends and very close to family. I have lots of friends I socialize with and am also close to family.
My partner has a tendency, from time to time, to talk too much. On our first holiday recently I gently told him that I need quiet time as well. He respected this and either left me to read/do my own thing or sat with me quietly.
However when I recently introduced him to family all that seemed to go out the window. He dominated the conversation at least 60% of the time and when we came in from a long day where we had a lull before dinner, I settled down with a book only to find him talking the ear off my family again. It stressed me out because I just wanted to chill for that hour and I think my family did too but we're too polite to say.
Overall he did ask family thoughtful questions from things I told him so I feel there's room for improvement as they seemed to like him although the review was 'very chatty'. How do I bring this up without upsetting him?
