Do not pay the back rent on his storage unit. You gave him ample notice where it was and what he had to pay. It was up to him to either pay the rent or get his belongings out of there. If he had money to have the car fixed, then he has money to take care of the back rent on that facility.
I would like to know how he's driving the vehicle without a driver's license. Is the car in your name and do you still carry the insurance on it? If you do, you need to notify your DMV that you no longer have the car and drop the insurance on it for now. Drop the insurance and advise your insurance company that he doesn't have a valid driver's license. This is not about revenge, this is about protecting yourself if he has an accident.
Notice how he changes up his demeanor when he gets messages from your BF? Now, he wants to look like a great guy in her eyes and is trying to make you look unreasonable and insane. Do not drink the kool aid that he is serving up and I am sure your BF knows what he's doing.
Do not be afraid of him. He is nothing more than a bully and knows that you will jump when he says how high. He sounds like he might fit in the disordered personality arena. So many of the things he says and does reminds me of that personality disordered...but that is my opinion from what I have read about him over the years.
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.
