First Rule To No Contact

First rule to going no contact,,,,,, don't tell them what you're doing so that they do it first.. it's a mortifying lesson but it will get easier with practice..
I'm sorry that you're going through his crap again,, it's painful and frustrating..
I encourage you to prepare yourself for the best possible scenario and worst scenario.. Can you imagine what the best conclusion would be for you and his behaviors? (or lack of him so no behaviors to think about) and then imagine and preparing for the worst thing that could happen and his behaviors.. It's an old trick my therapist taught me decades ago and I still use it and it helps me to think clearer about my situation..
