I have ADHD, autism and dyspraxia, and I won't lie, sometimes I have been a nightmare to cope with but I have never been abusive.
I have shouted, and I have been ever so apologetic for it, but I have never name called, given the silent treatment, uttered things under my breath, made snips and snipes about things not being good enough, changed plans to inconvenience other people just because I am in a bad mood.
In fact I have been abused by partners because they could take advantage of my disabilities, then get me absolutely worked up so they can claim I am the one with the issues.
Because I have been abused I have done a lot of therapy and here is what my therapist told me: don't pathologise their mistreatment of you. It can be easy to try and find a problem and go into solution mode but it isn't your responsibility to fix those issues. All you should be asking yourself is: am I being mistreated? Yes or no.
Not yes, but only once a month, not yes, but I was being kind of a nag, not yes, but they say they love me and they are nice most of the time, not yes, but they didn't get enough love as a child, not yes, but they are going through a hard time right now, and definitely not yes, but they may be neurodivergent. Certainly not yes, but they might change.
