Equal treatment is not always enough for everyone. A child with disabilities will get more special treatment from his parent, because he will need it. A more independent child might not mind letting herself in after school. Receiving the same treatment isn't the same as feeling the same pinch. You are more suited to tolerate a mono-poly relationship than Ka seems to be.
This is so true. I’ve accepted that she “needs” more attention and/or time than me and don’t have a problem with it. I am an introvert and enjoy and need alone time. Though I have trouble accepting that she “needs” more sex than me and struggle with inequity in this area.
After much hard work, I think I am better suited for this type of mono-poly relationship than she is. Like I said above, she would be more comfortable being a primary with any other relationships as secondary.
