So I met this girl in class, we made small talk, exchanged numbers, met up a few days later, chilled at her dorm, cuddled up, made out, then I went home. It's the day after and I feel a compulsive obligatory need to message her something even though I have nothing I want to say. I dont particularly want a relationship, but would like to keep this girl around. Wut do if I want to maintain this relationship? I don't want to ruin it with clingyness.
