I am a photographer, and I have a girlfriend who loves me very much. But I don't love her! What should I do?

Then you choose to tell her directly, which is better! You will hurt her no matter what. To tell the truth, you have hurt her! What are you afraid of? You'd better tell her directly Sooner or later, she will suffer such pain. Long pain is better than short pain. You are a photographer, you should have your own ideas, and you have the desire to realize your work! Your heart is big! And she's really not for you.
