SR71blackbird, there is truly nothing you more you could have done. When a person has diabetes they must take responsibility for taking care of themselves and no matter how much you try to encourage them to do so, it will only happen if they want to do it. Congestive Heart Failure is directly connected with uncontrolled diabetes. I tell you this because I just lost my husband of 23 years on Dec 13, 2012, to the same thing. He was diagnosed with diabetes 15 years ago and I constantly tried to make him eat right, excercise, take his medication, and monitor his sugar levels. About 5 years ago he started getting numbness in his feet but that still did not change him. Two years later he stepped on a nail that he did not feel and by the time he realized it, it had become grossly infected and they thought they would have to amputate his foot. Six months of aggressive treatment of antibiotics and it finally healed. That still did not change him. 2 years ago, he had his first CHF episode and was in the hospital for a week. Still no change. For the last 2 years his body was continually having problems with CHF then his kidneys started failing and he had to go on dialysis last year. At this point he was finally beginning to understand that he needed to make a change, but it turned out to be too little, too late. He died December 13, 2012. The one thing that I know is that I tried everything I could to get him to change his lifestyle, but like your boyfriend, he did not take it seriously enough to make the change to prevent himself from going into such a steep decline, not realizing they lacked the strength to climb out of it until it was too late. So don't beat yourself up, you did what you could. I loved my husband and I miss him terribly. The incredible since of loss is overwhelming at times but I know that I did what I could and he is in a better place now because he is no longer in pain. I pray that you will find comfort in my story and know that things will get better with time.
