Recently a girl I really liked branch swung and moved on to someone else. She has been wanting to maintain a friendship I'm sure for a fall back option, but I have no interest in that. However when she texts and calls for some reason I feel like I'm being a jerk if I don't respond or answer, I have this need to tell her I don't want to see her again. Is this normal? Should I say anything or just block her numbers and move on? I have no desire for a platonic friendship with this person, only a romantic one.
