Hi beautyfromashes,

I really like the name you chose. I'm sorry that you have had so much conflict in your relationship. I understand what it's like to stick around because of your faith.
It sounds like your husband may have struggled with shame and guilt after you laid out to him what you wanted to change in your marriage. That may be why he chose to leave. This sounds like a great opportunity for you to begin working on yourself, rebuilding your self worth, learning new and healthy ways of reacting to your H, setting appropriate boundaries etc.
A separation with the intent of reconciliation has often been shown to help heal many of the difficulties in a marriage because both partners get the space they need to determine what is and what is not important.
Does a decision about divorce have to be made right away or can you both live separately and work on things at the same time?
I believe there is always hope in a BPD relationship. My H and I have gone from constant accusation like you described, weekly rages, and general negativity to rare accusations (and if he does, he immediately apologizes), no rages for 3 months, and we are in a relatively great place (the best it's ever been in 13 years of marriage).It takes a lot of hard work though. My focus had to change from trying to change his behavior to looking at my own behavior and changing myself. From there I found the skills to validate my H's insecurity, address problems appropriately and in a way that he can understand, and to learn what my values you so I can set boundaries around those values.
We have some great lessons and workshops available that can help.To get you started, our lessons on
Understanding Your Role in the Relationship and
Stop Accusation & Blaming might help.
