Have a conversation at the beginning about what she is wanting from you. If it is just a listening ear, then be that (if you want to).
No matter how "nicely" you want to respond, it may come across wrong. She may just want validation.
The better you validate, the more you can respond and her not get defensive.
But bottom line, if you are good at validation and she is still hanging up on you, you need to set a boundary. "W, I am happy to listen to you. You have a perspective on all this that I am very interested in. I will ask you though to stop hanging up on me. If you want to end the conversation, thank me for listening and then hang up".
Teach her how to treat you. (and be prepared for her to not get this the first 5-6 times. Probably will take 10.lol)
