Yes, she say the wrong thing etc but have you taken some time out to go and see her and explain what the impact is she is having? You mention arguments but would it be beneficial to go out for a coffee and have a chat? You are a grown up woman and should be able to resolve this if tackled in the right way.
I'm not the OP, but I tried for years to resolve the difficulties between my mother and me - I arranged holidays just for us; invited her on days out; suggested meals; cinema trips; cared for her when she was post op; supported her through relationship breakups; had her round once a week for dinner etc etc etc.
It made no difference. Whatever I did wasn't good enough; she still 'told me off' at me in public; she still called me names; still lied about me to people...
She either knew or didn't care about the impact on me. She wasn't interested in having a relationship with me, she was interested in having, effectively, a 'whipping boy'. She was incapable of caring about me.
It's not possible to 'resolve' it if you are being abused because the other person is making a choice and behaving exactly as they wish to.
Again, we wouldnt suggest that an abused partner should just behave like an adult and just 'resolve' the issues she faced in an abusive relationship.
In the end, my mother's dysfunctional behaviours towards me escalated to the point where it was impacting on my children. I shielded them from her as much as I could (they were never left alone with her, phone calls were monitored and we stepped in as soon as she said something inappropriate to end the call) but she eventually overstepped the line, the police and the LA became involved and she was deemed to be a risk to them - no contact since.
Emotional abuse cannot be chatted and reasoned away.
