<human>: Can you succinctly summarize the text in 1-3 sentences?

I have been best friends with "Julie" since high school.  We both got married in our 30 - I am childfree by choice, she has two kids, an 8-year old autistic girl (very high functioning, mostly just a chatterbox who is a bit quirky) and an infant.

We used to have lunch once a week.  She is desperate for a break, I would say verge of a nervous breakdown.  Both her kids co-sleep and don't care for the dad, so she is not able to go out at night - ever. 

She is begging me to have lunch. I say -- ANYTIME!  But now she keeps saying "The 8 year old is crying, she wants to come with us, she complains she never gets to go with us to lunch" (it has been a year since we had lunch).

Then she puts the kid on the phone with me so I can listen to her cry, "I want to go to lunch with mommy and auntie, I never get to go, I will be so sad."

If we go to lunch with the kid, for one, it is NOT a break for her.  For two, the kid will monopolize the entire lunch.  She is able to sneak away for lunch with babysitting support from husband one day a week.  I want it to be the both of us.

Am I a heartless bitch?  Part of me doesn't want to deal, because that is not my idea of a very relaxing lunch for me -- but, I am happy to suck it up and do it for MY FRIEND, but I know this is NO break for her, either.
<bot>: Mandatory summary/question! My best friend puts her 8 year old kid on the phone crying to me that she can't come to lunch with us; we NEVER get friend time!
