Diabetic Partner - Just to say I hope the appointment at the doctors goes well for your partner.
Introduce him to this forum, he needs to lose the fear of diabetes, and the more he learns about the condition, and what he can do to control his condition the less anxious he will be. I am almost certain that he is pulling away from you because at this time he feels confused and helpless and frightened. I dare say most of us have felt like this when we were hit with the diabetes diagnosis.
He is lucky in that he has such a supportive partner in you, you both can learn about diabetes together, you will gain insight, confidence and feel empowered, and I really think that your relationship will become stronger as a result of it.
All the best to both of you x x
