A, Don't apologize about posting to several threads. You are new here and didn't know this. So, what you do is continue to post on this one and reply to the posters who come to visit. Once this thread locks (about 100 postings), you can then begin a new one with a new title, etc.
It's a very sticky situation that you have there. If he wants more time, then give it to him, but with the stipulation that he has to help support you since you going to be retired and that your pension won't be enought to live on. If you don't want a divorce, then don't raise the subject of the divorce again. It sounds to me like he's a very confused puppy and is trying to figure things out in his own way, which is do nothing but stay frozen, so to speak.
Make a list of your expenses and take it to the meeting with him. Be upbeat and whatever you do, try to remain calm and collected. He's not going to be able to handle much in the way of stressors then. If he gets a tad out of hand, just cut the meeting short and let him know that when he's ready to talk, you are available to continue the conversation.
I don't think he's going to go for renting a house in both your names. I suspect he's going to want you to do this w/o his assistance. I may be wrong on this, but when they are like this, they are trying to cut the ties in all areas of life w/us.
Continue to post; others will be joining in soon.
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.
