Chrissy, I have not read all of your thread recently but have had some of the less than normal experiences with an over bearing step father. I am older than you, he died around 1962, it took until my kids were out of the hous for me to drop some of the resentments, and I still come into a room and feel a little something where I cringe a little, when things are left on and no one is in the room. Almost no phone calls for me and you better not waste electricity. Sometimes he took the cord to the TV when he went out for the day and I was going to be home alone.
Your H sounds like he is mostly normal. I wash and dry clothes but rarely fold things. I am glad you are seeing he is doing what he thinks he can do for now. It takes time to make and adjust to changes.
Until I get to a point where I can concentrate on the forum a little more, take care of yourself.
