<human>: Can you provide a brief overview of the text?

My girlfriend [18] and I [19] have been dating for almost 4 years and I am absolutely crazy about her, but whenever I try to talk about something going on in my life, the conversation usually turns into talking about something going on in her life (or she gets frustrated). I want to be able to talk to her about things going on in my life/be able to vent to her (instead of going to another friend), but I don't know how to talk to her about this without offending her. How would I go about communicating my feelings to her without making her become self-conscious about how often she talks about herself or offending her? If this isn't possible, how should I talk to her?
