I am sorry that your dog isn't feeling well. Hopefully the tests will reveal what is going on with him.
I don't recall if you have ever stated that the mortgage is your name only, but if his name is also on the mortgage, the law may look at it as he is to get half of the equity of the home, i.e., regardless as to whether he's paying the his share of the mortgage or not. That would be something that should be discussed w/lawyers to ensure that there is fair division of property for settlement.
Do you want a divorce? If not, then you need to stop having discussions about the division of property, etc. You are planting seeds in his head that you definitely want a divorce. Are you hoping that discussions about it will bring him running back to you? If so, I don't think that this will happen.
I know you want him to know how you feel about getting back together, but you need to cease these talks for now. You are putting undue pressure on him to get his act together. He can hardly take care of himself at the moment. He needs the time to figure things out and find a path back to reality. Focusing on your comments takes him away from what he needs to do for himself. Since you have stated your thoughts, now leave it alone and give him the time he needs. Trust me, he knew before this last conversation how you felt. He also knows that you are waiting in the wings. He senses it and he also knows that you are way too focused on him and his life at the moment. Step back, live your life and just leave him be.
In my opinion, you should only contact him if it's an emergency, i.e., the dog or something else. He needs the time and space to get it together. He's not going to snap out of it any time soon because he's got a ways to go. If he senses you pulling away, he just might come to realize that you aren't waiting on him any longer and start pedaling towards you.
Keep the focus on you and your dog! Only contact him when necessary. Keep moving forward and no more relationship talks w/him at this time.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
