DEAR ABBY: Nine years ago, I severed all ties with my mother-in-law after she accused my husband of sexually assaulting his sister when she was in her teens. His sister died nine years ago from starvation after she was diagnosed with schizophrenia. Since then, I have not spoken to his mother. However, two of my children are recently married. I’m starting to feel guilty for not telling her that her two grandchildren got married. Should I say something to her? -- FEELING GUILTY IN ILLINOIS
