That could work LOL! Later down the road, he may explore a poly relationship again and things would be different, maybe not. You were his first exposure so he didn't have any developed skills or knowledge to pull through. Don't blame yourself, the way you see things is probably so totally foreign to the way he does that you can't be blamed for missing things.
The important thing is that you learned something and therefore are now in a better place to build something healthier and more positive in the future
