<human>: Summarize the given text in a few sentences.

So back on Veterans Day a friend of mine and our kids went to a fun place for the day and my friend snap chatted about it. Our other friend with no relationship or kids texted both of us in a group message and said we weren't being very good friends by not asking if she'd like to join. She said a multitude of other things about basically, how crappy we are and that maybe we'd "outgrown her. This friend lives like 30 miles away mind you and doesn't have a vehicle, which means I would've had to pick her up. We just spur of the moment wanted to take our kids somewhere.
My response to her text was probably a bit harsh. But basically I told her that I don't accept what she's telling me. That I rely on nobody for happiness besides myself and my husband and that it's unfair for her to back me into this corner because she had unmet expectations of our friendship that she never made clear in the first place. Her and I are pretty new friends but still had a pretty great connection. I also told her that her uppity text made me feel like maybe she'd outgrown us and maybe needed friends who don't have children who can meet her expectations that she clearly holds so high.
She recently met up with my other friend that was with me that day and basically told her, I'll hang out with you again but not me because while I am fun and great I was also harsh and didn't consider her feelings.
I don't know what to say. I thought eventually we would be able to make amends but it doesn't seem like it. How would you go about, at least get on good ground? Or would you just let it go all together? Was I too harsh?
<bot>: friend said I wasnt being a good friend because I didn't spend enough time with her and I told her to find new friends because I can't meet her expectations in life right now. She loathes me now.
