<human>: Can you give me the gist of the text in a nutshell?

The worst thing that ever happened during my childhood was my parents divorce when I was 10.

Childhood:
PROS:
*my dad paid off the house so my mom didn't have to pay a mortgage. Hard enough for mom to get back into working, etc.
*Mom worked her ass off for me and my two sisters.
*I basically got away with murder as a kid and teenager, took it for granted of course.
*Dad payed for school in full for all of us.

CONS:
*I was a rebellious teenager because my mom didn't have time for us after the divorce, i don't blame her for it though. She was doing what she had to.
*Herself and my sisters came first, always. I don't hold a grudge, but it keeps me from caring a lot of times.
*She believes that we had some form of great relationship while i grew up and it annoys the hell out of me.

Now I view seeing my mother as a chore. Her being involved in seeing other people like my sisters, makes me not want to see them either.
Im enjoying my life and i am happy. I am succeeding at work, getting fit, eating well, and living where I want. I get depressed when she asks me to come for her birthday and that my sister wonders why i dont talk to her.. when we never really talked.. i feel its all fake..
<bot>: Mom was a good mom, however me always coming last in every sense made me rebellious and not appreciate her. any sort of relationship we had was minimal and all the affection she spews now is fake and makes me sick.
