She prob in her own little way still holds something for you and cares for you. Thus the need to text you. Us girlies are like that, we sit by the phone waiting for you to ring or reply to a text. Then we weigh up the pros and cons of texting you. She is prob in a place where she feels she is strong enough to talk etc again, blokes normaly get there before us but in this case no. talk to her if you want and don't if you don't there is no one makingyou do what you don't want to. She prob doesn't have a specific reason for texting other than she thinks it was the right thing to do at the time, she prob v unawear of how you feel, either tell her or just leave it.
