I am in college and this is my closest and most obedient plate.

This girl I have been seeing has been really annoying me lately and keeps pushing me to commit when I have been really busy. I always tell her "I do not have time for a relationship right now", but she sees this as a challenge and tries to be the perfect girlfriend. She also drops hints every time we go out about meeting parents, going out holiday shopping.

She is trying to lock me down and I need to cut her off as gracefully as possible. It is time to move on from her, but she is constantly texting me. I do not reply and it only adds fuel to the fire.

Question: How do I naturally cut this girl from my life? The more I try to ignore her, the more she texts and tries to get me to respond to her. I do not want this to blow up and enter my other social scenes.
