Hi Inneedofhelp,
Welcome! I'm sorry that the prospect of divorce has causes so much upheaval in your relationship. Divorces are hard enough; the additional stress can wreak havoc on our wellbeing. I'm glad you joined the community, as you will find people who understand what you are going through.
Your plan to learn tools to help communication between you and your ex is a great one. And the tools you'll find on the site will help in
all your relationships going forward, too.
Seeing a therapist really helped me after my breakup with pwBPD—I'm glad you are planning to see one yourself. An objective, emphatic ear can make such a difference. Since you mentioned you were sometimes scared of your husband, I encourage you to think about a
Safety Plan. Even if things seem fine right now, it's much better to have an idea of what you will do if things do escalate, than run around with no plan in the heat of emotions. Hopefully you'll never need it, but it can give you peace of mind knowing that you have backup if things get out of hand.
By all means read as much as you can on the site. You'll learn valuable skills that will help you move forward. As

Turkish said, the Improving board has many great lessons that will be helpful for your situation.
You might also take a peek at the
Family Law, Divorce, and Custody board. Members there have been in similar situations and will share their experiences.
I know it's a lot of information to take in. Take your time and explore the site, and most of all, keep posting. We are here for you.
