He is harassing you loads, with all those calls about the DS. He is just keeping you on a leash over the phone.
Please take Solo's advice. If they can't take your number off the list and I am very surprised your number is on his list, given the circumstances, stop answering the phone when he calls, tell him one time (and record it) that you do not want him to ever contact you in any way ever again, and then take out an injunction and protection order.
That 'TY for sending me back to jail' shows he is as far from remorse as he is from the moon. You have to cut contact completely with this man or he will kill you. You must take every step available to you to ensure he never goes near you again.
You must go to Women's Aid and do the Freedom Programme. Call 0800 2000 247. It's a good thing that you have family available to support you and you are doing so many things right here. Do not waver.
This man is in prison because he committed a crime, not because you chose to put him there.
He committed the crime when he was already on probation for another crime.
Obviously he is not taking any sort of hint here that the things he is doing are not allowed or acceptable.
You cannot control any element of this situation.
You can't control what he does, and nothing you have ever done, whether pleasing or not to him, has ever made any difference to the way he has treated you. If it wasn't you it would be someone else.
You can't control the course the wheels of justice take. Let the police and the courts do their thing and co-operate to the fullest. They do not want to end up having to take you to a morgue in a body bag.
