Well when you talk to him, keep your emotions in check. You'll push him farther away if you lose it with him and start crying, pleading and begging.
It seems to me that you are jumping to the worst conclusion in everything he does. Maybe there it was a mistake by the DMV and it should have been in your name as well. If he purposely left your name off it because he wants a divorce then why keep the your home address.
I think it would be really good for you to start the IC again. You said yourself you are "reeling right now". This is a hard road you are on and you will need all the help you can get.
