Feeling bad- NC with uBPD mother - just got a nice text

[mntsmith]

So I've been mc with my mother for 2 weeks now- I'm still getting messages from her. It I haven't responded in two weeks. 99 % of the text have been nasty-  stuff like- she never said Anything mean to me ever- followed by  I'm disinherited, she so done done done with me to don't f@$&$@& come to her funeral or cry a tear for her ever-
Today's was simple and nice - I love you and what can I do do fix our relationship.
I know it's fake and it won't last- but I'm just feeling bad.
I'm not going to respond but was just wondering if anyone had advice. My children are completely done with her- my daughter been on the receiving end of having everything she said twisted around on her and for some reason my mom ignores my son. My husband think I just need to find a way to tolerate her- when I'm ready- he knows that's not now.

Never mind- the nice text was followed up by -- The Who do I think I am- text- I should respect her cause she's my mother and she never did or said anything wrong- I miss heard or mis understood her--- then another one  that's saying she never blamed me for anything ever--- HA!
How about like ever holiday for the past 13 years! I have ruined them all-  blames me for her finances, and it's also my fault when she misses activities for my kids! She blamed my daughter because she had to sell her house- said it was because we were too busy with our daughter to come see her and the house makes her sad with out us in it! Real reason- no one want to. BE trapped there with her! On the phone is bad enough!
Sorry- thanks for letting me vent!
