When you see him in a few days, if he pushes D talk, you do not have to agree to any terms or even discuss any terms at such an early stage even though he may try to pressure you. Tell him simply that this is going to take awhile for you to digest and you will be discussing it with the appropriate people in the next month and thinking about things. You don't owe him anything more.
I wouldn't even bring up health benefits and all that now. Just don't assist in speeding up the filing on your end in any way.
Have him sleep on couch if you are more comfortable. No, he no longer has the "right" to be in your bed.
This sounds like a hurtful situation all around. I think after a few night's sleep, you will be able to deal with it better than you think but that it will still be hard.
I'm sorry you are going through all this right now.
