I do not have much hope that it will change anything. My H needs IC, before MC will do anything for us. I do not think his heart is in this at all... I think he is doing it to show me how much he is trying.
I hope that these are all things you intend to bring up during your MC appointment. Hold his feet to the fire. If he's serious he'll take the heat - if he's not then you'll know it right away and not waste more of your time and endure more heartache then what you have already been through.
