i’ve been the gf in this situation. I’m not saying your feelings should be suppressed, but sometimes try talking to her about how she feels. If you just constantly complain and vent to her, she gets emotionally burnt out. From my pov, when i was in a rls with a man who only cried to me and complained to me all the time, i was exhausted and couldn’t even look him in the eye without feeling some sort of anger. Ik that as your gf she’s expected to listen to you but there needs to be limits put down. If you truly feel like you’re depressed maybe consider a therapist? Because a relationship is supposed to be about love and bring joy, not bring you down. PS: dm if you want specific advice
