Hi Scorpio2004, welcome to the group

Your situation sounds so difficult -- you want your H to get help, and if he chooses not to, you are ready to be done. Yet, he seems to hang on to the marriage (not granting a divorce), despite his contradictory attitudes and behaviors.
It's good to hear that you're trying emailing. In any relationship, when verbal conversations get emotional or escalate, it can be helpful to find other ways to communicate. What have you noticed when emailing instead of talking in person -- things going better/less heated, worse, other?
You're also not alone in coping with ADHD and having a PD (personality disordered) spouse. Can I ask, have you tried any therapy, counseling, medication, etc, to manage your ADHD? How has that gone?
Since you last posted, any updates in his behavior? Has he come and gone again, stayed at home, etc? How about you -- how have you held up?
I want you to know that your post is here on the "Bettering a relationship" board, even though you're pondering divorce, because at any stage of a relationship with a pwBPD (person with BPD), the tools and skills we learn on "Bettering" can help make things "less worse". In fact, when you have a chance, check out some of our tools (like this video on
ending conflicts) and let us know if any of it resonated with you.
Keep us posted, and again, welcome;
