As a person with BPD, what would you need to put in place to begin to rebuild trust in your relationship after emotional infidelity?

I've been sitting here thinking about what it would take for me to begin to feel comfortable in my relationship when there is no trust.

I feel like I would be a bit of a bunny boiler.

So I wanted to ask what practical steps, boundaries, etc, others with BPD would feel they would need to have to rebuild trust after lies, deceit and emotional infidelity?

Would you have an open phone policy?
Passwords to accounts?

Or would you work on blind trust?
