Hello AshleyE616

I'm so sorry you've been through all of this with your father. It has been very painful for you, I can hear this in your words. I understand completely how hard it is to watch your mother stay. BPD is a serious mental illness and these relationships can be very confusing. Has your father been diagnosed?
How are you doing with all of this? Have you considered a therapist for support with all you've been up against? They can be so insightful and supportive.
