Being married and having a relationship can take work. Keep trying.
You have done everything you feel you can do to keep your relationship strong with your partner and their diabetes. Marriage and relationships are important, and it is always best to work on a commitment that included communication. Chronic illness will strain any marriage or relationship. Keep the line of communication open, ask what you can do to help, be there to pick up the pieces, and avoid telling your diabetic partner what to do. Plan togetherness. Take walks together, eat the diabetic foods you make for your partner, don’t eat tempting sugary foods in front of them; these are just a few things that will help keep your relationship on track.
