I'm a 32-year-old male and my girlfriend, who is 32, finds work venting really boring!

I strive to be a supportive boyfriend who listens to my girlfriend's challenges and is there for her. I’m attentive when she talks about her friends, but I find it difficult to stay engaged when she discusses her work. As a tax crime investigator, her conversations often revolve around intricate tax codes and detailed processes, and I struggle to concentrate during these discussions. I genuinely want to connect with her, especially since she takes the time to listen to my work-related frustrations as a psychiatrist. I don’t want our communication to feel one-sided, but listening to tax codes can be quite challenging for me. What can I do to navigate this without hurting her feelings?
