Faith77,

I'm so sorry you are having to learn about BPD, although in some ways it will likely come as a relief. Sometimes having a name on an thing helps... .and it definitely helps to find other people that have gone through this.
I'm an ambassador here and it's my job to kinda "show you around" and help you get settled.
Please look to the right. Click on "choosing a path". Do some reading. Post your thoughts about what you have read.
I advise making sure your browsing activity here is private.
So... .can you post about more details of your marriage. Perhaps describe the last argument. Let me guess... .it's a recurrent issue that seems "unsolvable", even though you have made many attempts to solve it?
Looking forward to getting to know you. You've found a safe place.
