Reject her

"I can't do that, Caoimhe."

"I know," she says. "I'm sorry. I'll always love you, Jack, but you can do so much better than me. I won't bother you again, I'll let you just forget about me. It's what's best for you."

With that, Caoimhe rushes out of the room, face still plastered in cum as her tears start flooding. You're left there, mouth agape for a few moments. Eventually, you wander outside and chain smoke for hours, unsure of what to do. You feel like you've had your very soul crushed. It gets dark and you walk back to your room. When you arrive, you find a neatly-wrapped parcel on the front door, addressed from Caoimhe. Opening it, you find its packed with the various things you've left at her room, like your spare toothbrush, some clothes, gum and various other bits and pieces. Alongside it are the few gifts you've given Caoimhe over the last few months, no doubt now returned.

Caoimhe doesn't contact you again. From what you hear from your friends, she's stuck in a serious slump. You try to talk to her a few times to check in, but she dodges you every time. No doubt she thinks she's doing you a favour, trying to make up for her actions in some way, but it won't work.

That relationship is over now. That's life, you suppose. School's ending pretty soon anyhow. All you can do is enjoy the rest of your time.
