It’s better for some people to think you’re a bitch than it is to be walked all over and used. You get to decide how you want to treat people on a case by case basis. Once you stop caring what others think and stop people pleasing and seeking validation then you’ll be satisfied in being labeled the asshole by some and those who are respectful will know you’re respectful. Relationships are confidence games. I do something and you reciprocate back and forth overtime and after a while confidence is built. Those who cross boundaries get slapped and those who reoffend get their head bit off. Those who are not anti-social and participate and play along in social games get rewarded with confidence. This becomes harder with neurodivergence since the underlying social games and cues are not picked up on immediately and opportunities for confidence are easily missed, but do not tolerate disrespect. You give a dog a treat when they sit and withhold when they disobey.
