A Never-ending Story

For the first time since my son got divorced, he got to spend Father's Day with his son.  We thought this was a good thing, and it was, except for one glitch. My plan was to take everyone out to dinner on Sunday afternoon, which would necessitate having our grandson for most of the day before bringing him home.  In order to facilitate this,  his mother agreed to switch driving duties and bring our grandson here on Friday, while we brought him home after going out to dinner on Sunday. According to our son, the only way this could happen was if we did not come anywhere near their house.  She insisted that we drop our grandson off a block away and his father had to walk him the rest of the way home. She said this was necessary because she insists that my husband assaulted her years ago and would do so again if given the chance. Why she thinks this would happen when there would be several witnesses in the car, including her son, is beyond logical. She is, of course, delusional, but my son refuses to stand up to her and tell her so. At first I told my son that this was ridiculous and unnecessary, especially since she drives right into our driveway and up to our garage door when she picks up my grandson on his weekends here, and doesn't seem to  be worried in the least about being "attacked" by my husband during those times. Anyway, when we got there, I reluctantly did as my son asked, and waited at the end of the block until my grandson was handed over to his mother, at which point I drove down the street and turned into the driveway next to theirs to turn around and pick up my son. There were several people on their front porch, and I asked my son who they were. He said they were relatives of his son's stepfather. Now it all became clear: she had an audience. My first thought was that someone was going to ask her why we dropped our grandson off so far away from the house.  That left her free to spew her poisonous delusions about my husband, which she still can't get over making up. It angers me that she can say whatever she wants, true or not, about us and she continues to get away with it. She still texts insults and criticisms about us to our son and, while he says he saves them, I frankly don't see what help this is.The saddest thing about all this is that her flawed personality simply does not allow her to be in the least self-aware.  She lies with impunity and believes whatever comes out of her mouth, so there is nothing to be gained by pointing out the lies to her. She just makes up something else. It's a never-ending story.
