I'm so happy you have such a wonderful, loving husband.
Good job!! I know this may feel really wrong and awkward right now but you have to do what is best for your own sanity. Bart has become to comfortable with using you as his sounding/whipping post.
No, you did not do anything wrong! You set clear boundaries with him. I think it's very common for adult children to revert to child like behavior with their parents. Bart is simply having a temper tantrum. You have NOTHING to feel guilty about.
I'm sure he will reach out to you. He may need a some time. If you don't hear from him there is nothing wrong with you reaching out to him.
My time is early in the morning. I love the quiet of the house before my husband wakes. I do my yoga and then devote time to prayer. The quiet of the morning is my favorite time of day.
You are doing great SWOT!! You are living your life. EnJoy your weekend.
