I agree with DnJ on everything that he posted. As I stated earlier, you do not need to explain why you are doing things. State what you are doing in a short, but nice manner, and go on about your business.
He is an emotional hot mess, i.e., just like teens behave. He is all over the map and no matter what you do or don't do, he's going to find fault with it. Why? Because he honestly does not know what he wants. Even though he is home, he is still all over the place and his settling down and become a mature man may take up to 18 months.
When he starts his rants say "I'm sorry you feel that way" and walk away. When you do that, he has no justification for what he's saying. As for him cussing you out on the phone...hang up. He is not respecting you. You do not need to be treated this way. You are the prize and he needs to realize this.
Would you accept this behavior from a real roommate? No. I don't think so. So, start looking at him as a roommate and treat like you would a roommate. Be respectful, but also be firm with your boundaries and what you will accept in the way of behavior.
You are the prize! Don't accept bad behavior. Walk away or hang up the phone and do not engage with him when he is acting out.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
