Is it justified to feel the relationship was a waste of time?

So been sorting through emotions talking with family and hopefully soon starting to see a counselor who specializes in working with clients with autism but anyways my breakup that I experienced last year still resides in my brain and it’s reasoning that bothers me. Like initially in the beginning you want to disclose something like this because it’s massive and you want to give the girl the fair chance to walk away if she doesn’t feel that it’s for her. Well this girl stayed then when our breakup came she blamed everything on my autism and saying she didn’t have the empathy or patience to try to understand me which was a gut punch because I got it all wrong her personality she seemed so sweet and kind then her true nature came out she also claimed to be an empathetic person too so maybe you can only be in certain situations
