I know that this isn’t good DBing or detaching, but every time H does something like your H is doing, I see it as more of a temp check for ME to him. If he truly didn’t care, was truly over your R, all of that, he wouldn’t give two seconds to thinking about what you are doing with your time or whether you were with another man. And he certainly wouldn’t follow up with additional texts when you don’t answer. Now that I have said the above, try to detach from him again and keep up your NC— you’ve been so good at that this week!
