It looks like nothing has changed in the month since you posted the question about his contribution to a wedding based on changed circumstances. You say he has been like this all his life, so I don't know why you think he would change his stripes now. If he's in denial about the financial realities, I would think you would need to make an appointment with a financial planner or a marriage counselor, or both. Nothing is going to change unless you completely alter and upset the nature of the conversation and stop doing what you and he have done for all these years. It sounds like professional intervention is your only hope. Since this is YOUR financial stability and future at risk as well as his, please take some decisive action even if you have to go by yourself. If you have access to and control of some money and assets, I suggest you move them to an account or safety deposit box that he does not have access to. You really should squirrel away a safety net until you can get him to see someone professional.
