I've been with my husband for 14 years. I was just diagnosed with BPD last year while inpatient. My husband looked it up as we had never heard of it and said: holy, that is completely you. I had always exhibited symptoms, we just assumed it was a product of childhood trauma. We didn't know it was a thing. Yes I can be very difficult to deal with. My husband has always loved me anyways. With a diagnosis now I'm able to work on identifying and changing my behaviors. I'm in DBT and my husband fully supports me. I feel very fortunate to have been loved all this time with unidentified DBT. He saw the best in me, in spite of my issues and showed me that I was a worthwhile person. Before him everybody ran like heck.
