I have a few friendships like this. Where all the conversations we have are about that friends problems and about what they are doing. and they seriously blow off any of my problems like they are nothing or don't allow me to say anything about what i think is interesting.

I just quit talking to them. If they text or call me fine. I let them complain for a bit because I still have a little bit of affection for them but most of the conversations i keep shortish because we dont have much to talk about.

Maybe you could just keep any conversations she starts with you short? If she wants you to call her and it makes you uncomfortable just pretend like you didn't get her message, you forgot, or you didn't get a chance to.

People drift apart. Not talking to her after a while is normal.
