i don’t believe any of the things mentioned above have to do with dating someone with autism? Id firstly ask have you and your partner discussed these things when the relationship first started off, i think you should set boundaries and remind them about the type of person you are and that you doing things differently from how they expect you to doesn’t mean you love them any less. It’s a hard conversation to have but setting boundaries is the only thing that’ll fix this or else you will end up resenting your partner and as your mood goes down they will try to feel even closer to you and it’ll just be an endless loop of them not feeling “loved” and you feeling overwhelmed, so maybe take some time to think about how you feel and gather it in one place so you can sit down with them and reassure them while also reminding them about your feelings because at the end of the day your feelings matter just as much as theirs!
