Hi all. Here's some context. I (18F) have been struggling with BPD since my sophomore year of high school, so about three years now. It's a lot to deal with as you all know. My partner (20NB) and I have been together since January. They are my FP. We have an extremely close relationship that got very serious very fast, but we both love each other a lot and even moved in together at the beginning of May. 

&amp;#x200B;

I have a personal instagram account that I use to vent my feelings or rant or whatever to my closest friends. My partner has been following this account since the beginning of our relationship, and has even told me that they check my page daily to make sure I'm doing okay, because it's easier for me to type feelings out than to talk to someone about them face to face. I talk about my mental health and BPD and personal traumas in almost every single post. It's just what works for me. 

&amp;#x200B;

Anyways, my partner and I have been obsessed with Grey's Anatomy and we have been watching it constantly. Most of the cases on the show are brutal injuries or life threatening illness, but we were laying in bed watching an episode where a character gets diagnosed with BPD. My partner turns to me and says, "I always thought BPD stood for bipolar disorder, is it like the same thing?" 

&amp;#x200B;

I was so dumbfounded that they didn't know what BPD meant when I mention it so so much in my instagram posts that I could hardly answer them. I wish I would've just talked about it more, but I pretty much just told them that wasn't right and changed the subject. There's obviously more to it but I can't remember the entire conversation as I started to dissociate at this point.

I just cannot believe they didn't know what it was. When I talk about it literally all the time. I'm completely crushed. This was days ago and I have been in a terrible downward spiral since. I wish I would've just confronted them like, how did you not know about this thing that I talk about literally all the time? But I needed time to collect my thoughts and I feel like asking days later about that one moment would be too much, especially since they knew I had been upset about something and couldn't tell them what. I just. It's really upsetting to think this whole time that this person loved me for me and everything that makes me me, even my personality disorder. But they didn't even know I have it and likened it to "crazy" and "messed up" alcoholics and drug addicts they know. I'm just really hurt and I don't know how to handle this, because they weren't being an asshole on purpose, they just didn't know. But how could they not know?
