My neurodivergent girlfriend went from hypersexual to asexual and I dont know what to do

Me and my neurodivergent girlfriend have been dating for almost 3 years now. We started off as best friends with benefits and we were very sexually active.

Fast forward and we are the closest we have ever been to each other, but now physical intimacy is almost non-existent. We never kiss and the only times we do is a quick peck from her when I ask for one, and sex has been basically out the window ever since we started dating.

Edit to add: She has had past sexual abuse. I have asked her multiple times if I have done anything to trigger that or if those memories come back when we engage in sex and she said no.

Continued: She is also very stressed. I feel because of her neurodivergency she has not come to terms with going to work and school. She is very dreadful when it comes to going to work or an exam coming up. She also has a mother that is always expecting her to do things around the house. She doesn’t like her daughter to just lay around and my girlfriend constantly feels that she is lazy and unproductive for relaxing.

I have expressed to her how I have been feeling and she definitely expresses and sees my side. She has told me that a lot of it is very overstimulating for her now and she can’t seem to ever put herself in the mood anymore. Even when I try to initiate it, she is either almost grossed out by it or her overstimulation stops it. She also said that she does want to have sex with me, but she just cant put herself in the mood.

As much as I do understand her side and sympathize with it, it has made me feel very alone and empty. To me physical intimacy is a place where I can connect on another level with someone since it’s very vulnerable.

Everything else in our relationship is amazing, and I don’t want to part ways. But this has just been very taxing on me. Any help would be appreciated.

Edit: If it does change anything /g, we are a lesbian couple and both are 20yo.
