A great gift idea for your girlfriend would be a psychology-themed book, such as "Thinking, Fast and Slow" by Daniel Kahneman or "The Power of Habit" by Charles Duhigg. You could also consider gifting her a subscription to a psychology magazine, such as Psychology Today. Another thoughtful possibility is a personalized notebook with a cover design that features a quote or image related to psychology. Additionally, you could consider getting her a gift certificate for a local workshop or class on psychology, mindfulness, or meditation - something that she can learn and explore more in the field of psychology.
Or you can get her a star map with an important date you share.
