<human>: Condense the text into a few key points

I am just done with this friendship. We live in the same part of town and both have young kids, so I can't just cut her out of my life. I'm not mad at her and I want to still be acquaintances, but I am just DONE with trying to get together. 

She constantly complains that she never sees me, so to be nice, I make plans. And then I dread them, and they inevitably get canceled (not always by me, but sometimes) and then we start over again. The open invitation is along the lines of, "let me know when you're available to hang out!"
<bot>: I want to decline an open invitation with a friend. What do I say? I don't want to make her mad and I don't want to be mean.
