Ladies. I need help. My sex life is non existent.

It's my fault. I don't want sex. At all. Which is recent and I can't determine why. Its obviously negatively affecting my marriage. My husband is quite upset and very persistent which makes me not want it. We used to work separate schedules and I was able to miss him and surprise him with outfits and such. Now we work at the same place together, different departments but I still see him alot. We do everything together. Dont get me wrong I enjoy being on the same schedule but maybe not the same job but he doesn't have a license and is terrified/ has extreme anxiety about driving. His brother used to take him to work but they worked together on the same shift. If he were to get a different job there would be no one to take him and we only have the one vehicle. I just dont know how to rekindle my sex drive. I'm at a loss. Ugh.
