Hello I'm new here and have a fiance that has bpd and I'm looking at some new ways to help me cope
LifeWideOpen,

We are here to listen and support you emotionally.
"Coping" is one way to exist in a BPD relationship; however, I am going to suggest a more aggressive strategy to "manage it", otherwise it will eventually consume you.
If you have accepted her BPD diagnosis, I would recommend the book "Stop Caretaking the Borderline Or Narcissist: How to End the Drama and Get on with Life" by Margalis Fjelstad on how to manage the relationship to a point where it does not consume all of your energy.
There are many other resources, please keep coming back.
I am sure you are emotionally drained, be kind to yourself and do some self-care whatever that might look like for you.
Take care.
