I think you have to frame the way youre think about it differently. 🤔
It sounds like you’re thinking of this as having a need (like alone time or a different way to verbalize conflict) that you feel you have to prove is valid. It seems like the way you intend to prove it is by applying the autism label to yourself. Which, by the way, sounds right to me, but I don’t have a master’s in psychology. 🤷
All that to say, you’re a step removed from the real issue. Your need is valid. Just because it’s atypical doesn’t mean it should need to be "proved." I would hope that you and your wife are close enough that you can tell her what your needs are directly and be believed. I’d do that and ask her why it bothers her, and how that may be stopping her from getting her own needs met.
In other words, reframe it from "making a case" for why she should respect your needs to simply expressing your needs, asking for hers, and working together to meet both. You get what I’m saying? I had to do a similar reframing when I first moved in with my partner.
Also, you mentioned thinking your wife is sad, but she says she’s not. If you’re misjudging that, it fits with autism. 🤷 If she says she’s not mad, it’s not on you to decipher if she’s lying. Trust her; if she is lying, that’s her issue, to be honest.
