Maybe she does have a lot to study. Also, you broke up only one month ago. I'm friends with almost every guy I dated and I can tell you that it takes at least 6 months of not talking before you can become friends again. She answered you and that's a good thing. But I suggest that you leave her alone for a few months and let her process her feelings about the break up. Text her again in 5 to 6 months and I bet she'll be more reaponsive. The big question is why you felt the need to text her so soon.

That's because you are no longer dating each other, and she is not obliged to share details of her life with you any more.
