I was the "good kid" in my family. Did the things to be proud of, never made trouble... still am that way. Have my "stuff" together. And no one thinks a wit about me. I get invited over my brothers house on one holiday - Christmas. Why? So I can provide my nephew a gift. No one comes to my new house. No one thinks about my needs.

Sometimes literally if you are the good kid they think
- person X -- man I have to do this for him or that for him
- person Y -- there is so much to fix there
- person C -- if I don't resolve that ...
You-- oh he is squared a way I don't need to worry about him.

It is possible she could be so busy with the urgent issues she doesn't think a lot about you or even that you need her to care or show it.
