I think you did just fine. There's nothing set in stone that you need to tell him everywhere you are going and why. He is not your father. You are a grown woman who has errands to run.
He thinks you are cranky because you aren't being that lovey dovey wifey that he knows. I had to laugh about the bathroom. What did he think you were doing? Certainly not in there running the razor for a long period of time to cover up a call being made to a lover. Then again, maybe he's got something hidden in there and though you were looking around. You just never know what goes thru their minds.
Rednail, there is nothing set in stone that says you have to be happy all of the time. You are going to have days when nothing goes right and you are going to be down in the dumps. Being civil is good enough today and you have given him plenty to think about.
Be sure to contact some lawyers and get all of the info you need to help you make good decisions. Knowledge is power and the more you know, the more you'll be ahead if he does file.
Keep up the good work. Always try to remember, DB is for you. It is not to win your h back, but if the techniques work he comes back, then that's great. However, DB is to help you navigate yourself through all the loops of life. You can use it w/anyone at any 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.
