tired of justifying my choices

i am 34 and not married without kids.  that does not mean i don't want a husband/partner or kids.  it means it has not happened for me.  why do i have to justify my life choices to everyone everyday.  i am so tired of it.  i would like to have kids....maybe and i would like to have a long term partner, but i am not going to the sperm bank or just getting pregnant to have kids on my own.  if you wanted to do that with your life...that is fine.  i have no problem with that, but i am not a bad person because i lived my life different then yours.  i am tired of explaining every day at work.  when people say i am so maternal and i should be a mum.  fucking fantastic.  i would like to, but i don;t want to just go and get pregnant just to have a kid by myself.  i don't want to.  i don't want to.  why should i have to justify it to everyone. every day.  leave me the fuck alone.  let me do my work.  let me live my single life.  it is okay that your life is different then mine.  i am okay with it.  please leave me alone about mine.  i don't understand why i have to tell everyone why i don't have kids.  it is no one elses business.  LEAVE ME ALONE.  i guess i will never get that.  no one is going to leave me go about it.
