What do you make of this situation with this girl?

This girl i like hasn't responded to my texts in a week because we were suppose to go to a seminar together. So i completely ignore her in cl because i was pissed. Also i was plalying hard to get. Anyways, i felt so bad that i texted her saying hey sry abt not talking much today its just been one of those days. I feel bad for not wishing you a happy easter. She goes ahead and says awww (my name)! its ok! hope your day gets better...Happy easter to you too i know i pussied out when i wanted her to feel guilty for not texting me for a whole week and ignoring me. What should i do?
