SC I am so glad to hear from you. First off...that is a threat of physical violence. You should be calling the police. He is obviously dangerous and I hope you take his threat very seriously. I recommend a very good security system and that you watch your back very closely. Document, document, document. I agree, tell the therapist so they can help you also.
I am sorry SC. I think you are making progress, it is hard. Don't overlook how far you have come. You can do this.
Tight Hugs.
