Now's the time to change the supervised visitation, which is another way he is controlling you. I can't imagine that you would feel comfortable doing that and you don't need to. Part of his learning to live with reality is not getting his way and doing what's necessary, in this case having someone he doesn't know supervise his visitation.

Have you contacted your lawyer to talk about your fears of his being released and harassing you and threatening you like he has before?

Your son needs to be kept safe too.

I hope you will let your cousellor know you need more help with this.

I am so sorry you have this worry for you and your son's safety.
