Hi shep1166,
Welcome to the boards. You are in the right place to get some clarity around your confusion. I was in a long distance relationship with a woman who has undiagnosed BPD and there were times that I felt like she had played an emotional trick on me.
Sorry to hear about your father's passing. That must have been very difficult when also trying to negotiate the choppy waters of r/s issues. It sounds like the garage sale is very important to your partner and that must have been confounding for you when dealing with such a huge bereavement in your life. My condolences.
Here on the BPD Family website there is a wealth of information to help you make some kind of sense of the hitherto unfathomable. When I first came on here I was obsessed with how my pwBPD could treat me like a lover one day and something to be reviled the next.
I found this definition of what constitutes a person suffering from BPD very helpful:
To the family members, BPD behavior is often very frustrating can feel unfair and punitive - something like this (3):
You have been viewed as overly good and then overly bad;
You have been the focus of unprovoked anger or hurtful actions, alternating with periods when the family member acts perfectly normal and very loving;
Things that you have said or done have been twisted and used against you;
You are accused of things you never did or said?
You often find yourself defending and justifying your intentions;
You find yourself concealing what you think or feel because you are not heard;
You feel manipulated, controlled, and sometimes lied to.
As such, the most obvious "symptom" of Borderline Personality Disorder is a lifelong pattern of instability in interpersonal relationships, self-image and emotions.
I hope you will find this useful. You can read more at

I know it can feel like you are somehow endorsing outrageous behaviour, but people with BPD become empathically impaired when they get emotionally aroused. Validation skills can help take the intensity out of interactions and make it easier to have meaningful discussions.
More of that later. For now carry on posting on here and have a read around the boards. You will get some great support on here. Look forward to hearing more of your story.
