CG as always, great advice! Mystik, you already sound so much better than a few weeks ago. Just keep working at it.
I wanted to let you know how the supervised transition works with an agency. I researched it for my sitch when I D'd my first H. He was also an abuser. The way it works is you bring DS to the place and walk him in. Then, you leave while DS plays with a worker in a waiting room. After you are gone, your H arrives to pick DS up. You never see him. If you need to communicate something, I'd recommend a notebook that goes between homes. That way there is a written record if he tries to communicate something inappropriate to you. But most of the time, the notebook works well because they get scared to write more than just child notes.
