I went through something similar as the low-libido partner. It’s very confusing. Since she’s a woman, it could boil down to hormones. Stress can be extremely impactful on a woman’s libido comparatively, in my experience. I eventually bounced back but constant conversations about it just kinda stressed me out more and gave me a sort of performance anxiety.
Personal changes tbh. I was working a Saturday-Wednesday 3-11 am shift and only ever saw my partner and coworkers for months. Even when I did see my partner, it was for like 30 minutes when he was getting off work and I was going in. I wasn’t sleeping and I was overall miserable. Now I work a m-f 3-11 pm shift and I’m doing so much better and far less stressed
We also kinda “schedule” when we’ll have sex because I don’t operate well having sex on a whim. So that way I have the day to sort of mentally prepare and get in the headspace of wanting to have sex. I can’t speak for all women but I think a lot of us struggle with getting in the mood on the flip of a coin, it’s much more mental than physical for us
