Suggest Remedy For Stress Caused Due To Abusive Behaviour Of Spouse

This question is not really about me and my health as much as about my husband. He is a difficult person to say the least and it is getting worse the older he gets. We have been married over 40 years and they have not all been pleasant ones, but his disposition is much worse now than before. He had a heart attack about 3 1/2 years ago, but he goes for check ups and seems to be okay physically. I can do nothing right; everything has to be done according to his likes and dislikes; he is jealous of my relationship with my children, especially my daughters, and my grandchildren. They are his grandchildren, too, so I really don t understand. I never know what he will do or say next and it is getting more and more stressful. I have tried to talk to him about this, but of course, it is always all my fault and I am wrong. Please help me to determine what I should do next. Life is awfully short to live it in constant upheaval. Thank you!
