Hi and welcome to the community! 
Unfortunately, I can't see your original post, because it's been edited out. But, from what I can gather from some of the replies, I thought I'd just mention this book, which I've personally found useful (as the autistic one in my relationship).
It focuses on helping couples in which one partner is autistic to improve their relationships through better mutual understanding and communication, complete with exercises that can be completed and discussed, if you wish:
Loving Someone with Asperger's Syndrome: Understanding and Connecting with your Partner
(It was written when "Asperger's" was still a diagnostic term, whereas it's now simply diagnosed as autism / Autism Spectrum Disorder).
Caveat: between one issue / scenario and the next, the author keeps switching the couple around. In one scenario, the male is autistic, but in the next it's the female, etc. This can be confusing, and I kept needing to check "which person is autistic this time?". It's not the only such book to have been written in that way, and I found it frustrating - but still a very worthwhile read.
You could also perhaps consider some couples counselling, led by an autism-experienced counsellor.
Also guessing / "reading between the lines" from some of the previous replies, your partner might find the advice here helpful - as well as perhaps joining (or just browsing) this community:
