How does one begin to break the chains of being a co-dependent?

I am not one to put my personal business on here. But...I'm trying to figure out this guy.

My child was sick. He stayed with my child and watched TV with them while I went to the grocery store. It was dark, cold, and raining.

I came back from the store and asked him if he would help carry the groceries into the house. I had already made a trip. Btw, I have a bunch of steps out front. He stood in the door and asked, "Well, aren't you going to help?"

I told him that while he was watching TV, I was loading the car up with groceries while holding an umbrella in the rain and cold and dark. Couldn't he help bring the groceries in? He said that when someone asks for help, that means that he's helping them and not doing it all.

Another time he was getting to broil a steak. I have a new stove and the broiler pan was dusty. He stood by the sink and as I walked into the kitchen, he asked if I would wash it. I asked him if the sink was too far from him. He washed it.

This week he watched my child while I went somewhere for an hour. I was running late. I made dinner, feed them and flew out the door. When I came back I saw that the remaining food was still on the stove. I asked him why he didn't put the food in the refrigerator. He said that I didn't ask him to do that. He then said, "Well, you ate too."

He thinks my child doesn't need to wear a bike helmet when riding the new adult sized bike they got for Christmas. Said my child didn't need it to ride on the sidewalk of my street but would need it if riding around the park. I want my child to wear it all of the time. I just put this in here to show how he thinks.

Sorry it's so long.

Damn robots.....
