Wife recently diagnosed with BPD

Good Morning, I am looking to find support as a loved one of someone with BPD. I have known since we met that she struggled with PTSD etc and her triggers were vast. When she would get triggered we would fight and she would be extremely mean with her words, and constantly threaten to leave and divorce me. We have always been able to communicate and resolve or at least address issues, after she had time to calm down and process her emotions, usually the next day as she takes a very long time to come down from a split. Leaving her alone was very hard for me to learn. But I love her and support her 10,000%. I won’t go nuts with all the details but she recently had a major break, or split, as we are learning it’s called, and it resulted in a suicide attempt, the police and her being hospitalized for 2 weeks. She came home with the new dx of BPD. I’m struggling and really need support from others living with a BPD loved one. Thank you
