husband jealous of my mother

[Guest]

My husband is actually jealous of my mother. He sulks, he is grumpy, he won't give her the time of day. My Mom is 84, and lives in a home for the elderly, nearby. I love her dearly, and I don't feel as if I sacrifice anything when I do something for her. My question is: is this a form of abuse that my husband is practicing. Hardly a day goes by when I'm not depressed or crying because of his attitude. We've been married 30 years and have 2 grown sons. I have my own business, and my husband (retired) works with me. I find myself trying to avoid him. It has gotton to the pont where I can't forgive his attitude anymore. As I write this, I can imagine I have only 2 choices. either accept him or leave him. I'm going on 60, and quite frankly I don't know where I would go. I never expected my later marriage years to turn into a divorce drama. I'm grateful for any suggestions. Thank you.
