Wendy, You are going to find that you have difficulty getting things done because your mind is whirling over what your h has and is doing. Also, you may be suffering a little bit of depression as well. I know it's difficult, but you've got to take your focus off of him in order to stay focused on what you need to do.
As for tenting for termites...if he doesn't think you are doing it fast enough, he knows how to pick up the phone (quite well I might add) and call them himself.
I do get the sense from your postings that he looks to you as a mother figure or his keeper...you will need to start thinking of ways to change that just a bit. He needs to grow up.
Please take care of yourself.
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.
