I think that you need to try and understand that this is not about you. Your Husband needs to sort things out and until you step out of the way and allow him to see that you are truly moving on in your life he will not be phased at all. You do need to be kind and respectful to him. MLC'ers can not handle angry confrontations. You need to remain calm so that you can avoid being baited into a fight. You need to stop the cake-eating but NOT as a punishment, more as a boundary for yourself. He needs to see that you have some self respect and will no longer be treated as a doormat. You can do this with your actions, not your words. Just take one day at a time for now.
There can be no testimony without a test. I am praying to go through this test and come out the other end with a new and better marriage then before.
