<human>: Lotsa details, please bear with me. 

My mom and I have had a tumultuous relationship for many years now. Right now, we're in a good spot, and though the underlying issues will never be resolved (she refuses to see a mediator/ counselor with me and my husband), she's visiting us for the first time in 4 years, though I've taken the kids to see her. She's on the other side of the country, so big trip.

When things were really bad with her, I would talk to her neighbor and friend. I said things about my mom that in retrospect I should have said only to my therapist or husband. She was saying bad things too, like being a gossip. Her neighbor is a drama magnet, would call to talk, and pull it out of me. It felt good to talk to someone who knew my mom. In hindsight, it was a terrible thing to do, on her part and mine.

Lately, the relationship between my mom and her neighbor fell apart and they aren't talking. It sounds like a many-faceted drama that was inevitable. I don't know all the details, but mostly from my mom since her neighbor hadn't called me first. But now she is calling, and has left 3 messages on my phone saying I "owe her the respect" to call her and hear "her side" and that my mom "yelled at [her] in public," among other things to try to get me to call. 

I'm afraid to call her and get sucked into her drama, when in fact, I should be loyal to my mom. But do I owe it to my neighbor to listen to her side? I'm also afraid she has things on me, the things I said about my mom to her, if they ever do mend their friendship and I've shunned the neighbor.

Can you condense the text into a few key points?
<bot>: My mom fell out with her neighbor, who was a confidante for me. The neighbor wants me to call her and talk about her side of the story.
