Dear Nicold W.,
First of all pray and ask God what He would want you to do.
The way I see it is this: your husband is choosing to do absolutely nothing that he is being told by the doctors and perhaps he is scared that something inside is acting up but afraid of having open-heart surgery again because he knows they have to saw open the sternum again and he knows first hand what kind of pain that is. Maybe the only way you can wake him up is have a legal separation and move out with your kids. This would make him totally responsible for his own bills (I think. Most lawyers have a first-time visit free and you can ask these questions) and he would not get to see his kids as much without making arrangments with you. Perhaps he needs a shock like this to wake up and do the right thing.
Many years ago I was going to divorce my husband (even though I knew in my heart that I would not be any happier without him in my life and that God HATES divorce). My husband cried and I knew that I caused that and it hurt me to the core and I changed my mind about divorce. But my point is that sometimes it takes a shock to wake up a person to see what is actually going on.
Perhaps your husband is depressed and scared about dying and knows that he will need serious surgery again in the near future and hates the fact that he has no choice to go through with that kind of pain again or die. He needs to read his Bible and get closer to God to find out that this life is not about us, but about serving and living for the one true Almighty God who created the Universe.
I was talking to a lady at Sam's Club a couple of weeks ago about my husband's health problems and she told me that anybody who has heart problems should go to the Cleveland Clinic and they work miracles. They work out with your insurance how to get everything paid. She said that her sister drove from MI to the Cleveland Clinic and went to the ER and was admitted and they did her surgery a couple of days later and she is so much better now.
I belong to Remnant Fellowship Church. They offer Bible studies that teach you how to put yourself last and God first and then God works out all the little minor details that we call life. You can contact them at www.weighdown.com. It is not really about the food. The same principles that pertain to not over eating pertain to not being self-centered, not over talking, not over spending, etc. Your husband could learn how to lay down the Mountain Dew which sounds like one of his idols. Or you could get into it and he would want to change by seeing how your life changes as you learn how to turn it all over to God. The most powerful Bible study they now have available is called "The Treasure Series." All their Bible studies are more in depth and scripturally accurate than any I have ever taken in my Christian life. They make a payment plan that you can handle even if it takes a while because it is not about the money, but it is also a business and the class costs money to produce and maintain all the tools that go along with it.
I hope you will check into weighdown. It has changed my life for the better and I want to get closer to God to learn how to lay down all my idols and leave them dead for good.
