My girlfriend (26F) has begun to connect her thoughts about me with emotions from her childhood trauma related to her father. I'm a 30-year-old man, and I'm wondering if there's anything I can do to help.

I've been in a wonderful relationship with an incredible girl (I'm 30, she's 26, for context) for nearly a year. Our time together has been filled with love and happiness, perhaps the best we've both experienced. However, last week I brought up that she seemed a bit distant, sensing she was stressed about something. She's not one to easily open up about her feelings, so I received the typical “I’m fine” response I’ve come to expect. I know she has some childhood trauma related to her biological father, who is no longer in her life, but she hasn’t shared much about it. It turns out, my comment about her distance made her feel like "my love isn't enough for him," which led to a serious panic attack at work, requiring her parents to come to her aid. Throughout last weekend, the panic attacks continued, and she unexpectedly cut off communication with me. When I reached out to her stepfather, he explained that her feelings of inadequacy are triggering memories of her father’s absence. Apparently, she hadn't experienced panic attacks in over a decade. Her stepfather conveyed that she intends to end our relationship, though several family members have suggested she doesn't truly mean it. On the positive side, she started seeing a therapist today. What concerns me is that her mother suggested she contact me for closure, which seemingly prompted another panic attack. I'm worried she’s beginning to associate me with the trauma of her past due to a misunderstanding of my innocent comment. I truly adore her and had plans to propose soon. Right now, I’m giving her space and maintaining no contact. Is there anything else I can do? I hope her therapy helps her objectively revisit our wonderful relationship to realize that I’m nothing like her father and that she is more than enough for me. This situation has hit me hard, as it all came so suddenly, and I feel helpless in wanting to support her. Thank you for any advice!
