Must be MIL from h#ll day, I had issues with mine as well! Would you be willing to block her number on your phone? No matter what your H is telling her, which would most likely be the typical MLC jibber jabber of nonsense, she does NOT need to be texting it to you. She is completely out of line and needs to stay out of your marriage, but because she sounds out of her mind, I don't think she will.
Do you need to have contact with her? If not, consider blocking her. To read and or hear her garbage brings no good into your world.
