I'm an autistic who is particularly unsympathetic to other people's meltdowns, especially if they are destructive of property or involve noise. Over time, I've come to the point where if a partner's behavior is more about their mental issues and less about making things good for me, I'm not too interested.
I was dating a man who I now believe was autistic as f**k. I was getting ready to go to the hospital for surgery, and he got upset with me and started yelling. One of his gripes was that I hadn't told him what kind of surgery I was having. In any case, that was the beginning of a long platonic friendship and the end of a romantic one. When I am going in for surgery is NOT a time for me to be yelled at! And if he would do that once, he would do it again, I was sure.
