DEAR ABBY: I have had a wonderful relationship with my only grandson for nine years. Since I retired, he visits every other weekend, which makes me so happy. He has autism and didn’t speak for the first six years, but now he talks constantly. It’s wonderful. I’m very close to my son as well.

I guess you know what’s coming: My daughter-in-law cut my grandchild out of my life four months ago. She says he was molested in my care by my husband. I took my husband of 13 years, who has never been alone with my grandson, ever, to the police station. He passed all lie detector tests, and the police said they believe my husband.

My grandson didn’t say a word; only my DIL spoke. I had CPS come out and they did a thorough investigation. They said that, in their opinion, she was making this up. She hasn’t spoken to her family in 12 years. She cuts everyone off if they upset her.

My grandson needs me. What can I do? My son says if I move and live next door to them, I can see him every day. But I don’t believe that would last either. I’m sure she would just come up with something else. Any ideas? — ACHING HEART IN TEXAS

DEAR ACHING HEART: If your son is suggesting that you move next door — presumably without your husband — it is a nonstarter.

The person who could fix this is your son. Because the accusation your DIL made was groundless, your son should insist you have visitation with your grandson. However, if that doesn’t happen, then remember Texas is a state in which grandparents DO have some rights. Therefore, it may benefit you to discuss this matter with an attorney specializing in family law.
