ThePinkDog,
That is such is sudden, drastic thing, to off and move and take all the cash and belongings.
I do realize that I helped trigger him the morning left because I was upset that he did not want to go out of his way to say goodbye to me
This is nothing that should contribute to running off as a newlywed. He was already going (if I am reading this right) so it's not about you. it hurts you, but it's really all about what is going on up in his head. He has already been dysregulated enough for you to learn of BPD and find this site. We are not responsible for their emotions, as much as they may claim we are and we may feel we are.
There are a few things I'd like to see if you can do - talk to your T as much as you are allowed/able. You need someone to help, let them know you are drinking away the pain so they can help there, too. Talk to your minister as well, see if maybe there is a group for people in emotional duress you can join.
Next - Have you spoken at all to an attorney about this? I know you want to honor your vows. Speaking to an attorney does not mean you want to divorce, but you should take some steps to protect your own assets. This does not mean your H is a bad person, but he is uncertain in his choice of actions and you can't live waiting for the other shoe to drop.
Sadly, there is often little we can do directly to help our loved ones with BPD. We want to get them into T, get them medicated, but BPD is resistant to both of those. Drugs don't really exist that treat BPD - they can treat depression, anxiety and maybe the PTSD, but not BPD itself. It's an emotional disorder. To treat it usually takes an uncommon amount of self-honesty on the side of the person with it, and honesty to accept they need to work on them. This often can come, but it takes a while and usually we need to be the stronger in the relationship about this.
We work to heal ourselves, keep ourselves strong, to establish boundaries between their emotions and ours, between us and hurtful actions they take. We learn, if we stay with a person with BPD, that they will not always be able to be a rational supportive partner - they are starting out way behind the start line in terms of emotional stability.
here are some lessons for those working to keep the relationship, for you to read and see if any can apply to your situation.
https://bpdfamily.com/message_board/index.php?topic=56206.0You say he is still telling you he wants this marriage. Work on determining what you want as well - what will you expect from him, in things to do and not do? How long do you think you can be in limbo?
You did not cause this. Please believe that. Please keep in touch and let us know how you are doing
