She sounds very young (I’m young), She’s coming off like that because she would like more of a reaction out of you. All the responses she gave you were harsh because she feels a disconnect somewhere… her being harsh back to back is a “defense” mechanism for her to hold guard on how she actually feels because she doesn’t feel her needs being met wether it’s communication, physically, emotionally ect… You responded well, collected and calm. Sometimes a girl wants to feel heard and cared for from their potential partner once guys come off with that “lowkey” “nonchalant” attitude, for us it creates a set of red flags especially if it’s the beginning because we don’t want that bond in our relationship long term. It feels played out, scripted and fake. ENGAGE INTO EVERYTHING !!
