I'm a 19-year-old guy and I'm thinking about ending my relationship with my girlfriend, who's 18. I’m feeling really conflicted and anxious about it. What’s the best way to go about breaking up with her?

We've been together every day for nearly five years, and she is truly in love with me. Yet, I find it incredibly difficult to look her in the eye and tell her that I want to move on and explore new relationships. I'm uncertain if I should feel guilty about this. She is kind-hearted and wonderful, but I've reached a point where I no longer wish to be in a relationship. After relocating to a different city for college, she's been struggling with the change. She calls me constantly, often in tears, expressing how much she needs me. Meanwhile, I'm left feeling emotional—not because I miss her, but rather because I don’t feel that sense of longing at all. I hesitate to end things because I know it will deeply affect her, and she doesn't deserve that pain. However, I also recognize that I shouldn't remain in a relationship if I don't truly want to be in it. It's a difficult situation, and I’m unsure of what steps to take.
