I know I owe her obedience because she is my mother and despite her beliefs I must show example of meekness at all times. This last Saturday after we argued regarding our country's Referendum on redefining the Constitution about marriage left me especially sad and tired and with an obsessive prelet that she is actually enjoying bringing me down (which can't be a vision from God who sent me to her to be her daughter in the first place and He makes no mistake).
I do not live with my mother. I visit her regularly and even so I feel some sort of guilt and pressure towards her every time she expresses her disappointment in my spiritual life. When I was teen and going to church and confession far more often than now she reacted the same way.
I'm sure that you are already praying for your mother and seeking the Lord's guidance on how to handle this difficult situation.
If this were me, I'd focus on treating her with respect, trying not to get angry, and using humor.
You might try to diffuse her verbal spars with humor. For example: "Mom, you know we disagree on this topic. I love you too much to argue with you, especially when I know you're wrong, (big smile) so let's talk about something else. Where shall we go for lunch?"
Then refuse to discuss any topic with her and use humor to dismiss her attempts. If she keeps after you then stop the conversation, tell her that you won't stay if she only wants to argue, and then ask her for a hug before you leave. Then leave.
My expectation is that it would not work at first but that eventually she'd give up trying to get your anger up. And if you are forced to leave she will find more respect for you and not push (since the price for pushing is not seeing you as often or for as long on each visit).
For you, at first you will be diffusing her with humor while boiling inside. But over time you will be able to control the anger.
