Hi crdnl and

I'm sorry for the circumstances that brought you here but I am glad you have found us.
Leaving a BPD partner can be very tough, even if we know that it is the healthiest choice we can make for ourselves. Is there a particular incident that led to your decision?
I understand the second guessing. It's very hard to know if we are making the right choice sometimes, especially if we have been subjected to lots of blaming and criticizing.
I know how hard it is to struggle with the guilt, as well. It took months after going no contact with my ex before I was able to let go of the guilt. I felt responsible for his pain regarding the breakup, even though I knew that the relationship was not healthy or safe for me to continue. I found a good therapist who was able to help me explore where my guilt was coming from and help me to work through it.
Have you had a chance to look around and read some of the articles we have here? There is a lot of good information, and I think if you settle in, read and respond to others' posts here, you will find that you are not alone, and many of us have been or are still in a similar situation. We're here to support you, and we are listening.
Blessings and peace,
Redeemed
