My wife with autism has been distant

My wife (ND) and me (Male NT) have been married for several years now, and I have been experiencing her easing on her normal actions of intimacy to me. She has been kissing me less, stimming on me less, or hasn’t been snuggling in bed. I’ve tried to talk to her about it, saying things like hey I’ve noticed you’ve been a little distant lately, or telling her I miss her, but nothing seems to make her want to be close to me.

I love talking to her about her day and having non touch intimacy, like doing her favorite puzzles or board games, but it’s been hard losing the comfort she would give me when life is difficult.

It’s been very hard on me as she is my safe place and I’ve been very stressed with work. I was wondering if anyone had any advice or would wonder what to say to express my feelings of missing her touch or her love?

Thanks!
