Keep venting here and not to him. Yes his comparing this sitch to 10yrs ago makes no sense buy don't tell him that.
I did not start db till after my husband moved out. When he was living in the house I said all the rational things that you want to say. I told him he was being a jerk for doing this to his kids. That he should have mentioned a problem before it was too late. And on and on. None of my common sense talk worked.
You are lucky you have found db and your h is still at home. Somehow you need to find the strength to only express your normal feelings here and act honky dory with him.
Big hug
