So a little bit of background: we were in a LTR for 4 years (both 20 years old) and broke up 3 months ago because we were growing apart and had very different plans for the future. Ran into her a few times since then and we still get along great, which makes this whole thing harder for me.

Once a week she keeps sending me a snapchat or a text regarding random shit like her job/festivals/other casual topics. I don't respond to her snapchats and give her very brief answers via text. She still keeps hitting me up once in a while. Why is she doing this and what should I do? I feel like I'm being a complete asshole if I don't respond to her texts or cut her off because we broke up in a good way and I'm not angry/pissed at her whatsoever.

Note: I have no interest in getting back with her, but I have to admit that her messages still slightly do something to me.
